Contractual good service underground

Advance the positive: fast delivery, rapid activation and super power volume at a great price. The website is appealing and self-explanatory. Many settings regarding the contract can be carried out independently.
This acute price is but a miserable service counter:
Background: Since I have a new number with this contract, I have to my friends a (group) SMS sent with an appropriate note. This SMS was received by many people 3-5 times. Even later messages have been received very late and / or multiply. This still very annoying disorder I wanted to follow me and contact support. After all, there is indeed a suspicion that the system 5x sent SMS are also charged 5 times (do with a phone book from a lot), for which I so in the end nothing can. So the hotline number picked out and called ...
Meanwhile, I've been trying for 2 days to call the service hotline and it always comes back the announcement, there were all consultants involved in discussions and due to the high customer Andrangs I should try it at a later time again. A hold and thus being able to hope someone speaking does not exist. It's really strange that on its own website so advertised:

"Your Service Guarantee
Customer Service & Delivery
Service guarantee

-Beantwortung All e-mail inquiries, complaints and appeals within 2 business days. (Bayern width holidays and Saturdays are not considered working days)
---> A short waiting period in the hotline: The maximum average waiting time in the queue is for customers who identify, 90 seconds. (Hotline weekdays Mon-Fri 9: 30-17: 00 clock) -With speak to the supervisor: If you are dissatisfied, you can talk with the team leader. "

Where please is this "short" waiting time of 90 seconds (I'm waiting now 108,000 seconds (30h) ... which raises the average enormously !!) ?? Do you have only one person on the line ?? What is, of course, of course, is the fact that despite a huge customer rush on the lines over time (16: 55Uhr) are closed. Furthermore, it remains unclear whether any call that has indeed brought nothing, what costs or not.
Talk to the team leader ?? Something exists ?? The should also grab the listener time ev..

It should be clearly rectified because such service is not looks.
Since I am a persistent person I'm going to keep trying. Up to a response from the hotline, the two points remain but first. This again I forgive on the positive points mentioned initially.

UPDATE:
on the third day of my call efforts, I am then come finally ... a recorded message that my problems (questions about an existing contract) was ready with a new 12-digit number and this act in 3 seconds manifest (optimal for the record). Why is a two days told that all client advisors were talking, when then only a recorded message? Likewise, a redirect to the new number would have been much customer friendly, but good. So called new number. For questions about !! existing !! Rates the number is 061817083094 indicated (so that others can call right there). So phoned times there. After a brief announcement that one should his number and have to know the password you will be stuck in a holding pattern ... 4,5 minutes later (as was the time to 90sec?) Then comes the announcement that all account managers were talking and I later should re-call, end the call. DO YOU WANT TO kidding me? That can not be said at the beginning? No one can wait and consume minutes people. Next update follows.

UPDATE 2:
At last I'm just gotten through to cro, this could also clarify my concern satisfactorily. According to her, there was an error in the system and the multiple SMS sent will only be normal, so just settled. Whether this is the case, I'll see with the next bill. Ultimately, the achievement of this statement was a time-consuming act and the capacity of the customer should be eventually checked again and be adjusted with increasing customer numbers. To satisfied clarify I forgive another point. More than 3 points overall I can not enter due to weak service. If you need help, then I do not want for 3 days rumtelefonieren until I reach what.
