Use G Data for a year and wanted to extend to upgrade. The registry key (Key), you can buy the case is, however, not accepted. Error message: "is already registered". That someone else has already used the key is hard to imagine, because the package was still originalverschweißt.
So searched on the website the number of customer support out, the 'round the clock every day' is reachable alleged. In fact, going off just an answering machine, which proclaims that 'all people are in a conversation' and ended the call. About a good two weeks, I have now several times a day my luck trying to have had every conceivable times and never success. There is not even a phone queue, so you would be connected to the next available employee. Either there is too little / no telephone operators, or exorbitant many customer calls.
I feel helpless. A written contacting the support is not possible. I have tried my luck in the mail, but after the already scarce two weeks ago, I have now today resorted to Russian competitors. Sure there are plenty of other buyers, which could enable their key problems. Nevertheless, a star in my eyes still too much when you consider that I do not even the purchase price will be refunded.
