I ordered goods worth over 650 at 14th of July.
As I was not satisfied with fit and quality, I sended back the goods within the 14 days. The package arrived at NOHOW at 1st of August.
After 21 days of not receiving any refund I sent an e-mail to NOHOW. They confirmed that the package has been received and ensured me that the refund will be send immediately. On 9th of September I still haven't received the refund and asked again. Same answer.
Today, 8th of October, over 2 month after my return package arrived at NOHOW I still haven't received the refund.
When I opened a paypal case they even started negotiating with me about the refund amount.
WHAT YOU CAN DO IF YOU HAVE THE SAME PROBLEM
I consulted my attorney and he handed me out the advice to initiate a legal dunning process (in german: Gerichtliches Mahnverfahren). You can buy the form in a stationery shop or download it online and hand it in to a german court. You have to pay for the effort and translation but in the end NOHOW is legally bounded to pay you back all the extra costs you had to pay to get your money back.
