Pearl Disappointing business partners

The device did not match the description. The descriptions on the packaging and instruction manual on / off switch does not exist. In spite of my immediate complaint, I received no device with switches. I was only refunded the amount back. The biggest disgrace was that I still wait until today to the reimbursement of transport costs. The mail order company Pearl, which stands behind the sale writes only impersonal standard mails. Customer is different! I can only advise against Pearl.
