WMF PermaDur Element Fry Pan 20cm

Very very bad experience. I purchased WMF PermaDur Element Bratpfanne, Ø 24 cm, within 7 months, the coating layer started coming off. I raised a complaint to the customer service, initially my request was ignored saying that it is not a defect, even though it has 5 years of warranty. After few emails and argument, one customer service professional agreed to provide me a value similar to the pan to purchase something else. I wanted a replacement. Then I was told that this pan is not available anymore and I have to choose from other products. I chose another similar pan. Then I got a confirmation email stating that the pan was ordered for me free of cost and I will receive this soon. After that no reply, no order confirmation email, no sign of receiving anything. Sending email to customer service, the email does not get delivered with a message that:
"Delivery has failed to these recipients or groups:

Internal Email Direct WMF DE ([email protected])
The recipient's mailbox is full and can't accept messages now. Please try resending your message later, or contact the recipient directly. "
The contact form does not work in English.

Again another person from customer service sends me an email asking for tracking number for returned item. I was never asked to send anything back by WMF, rather I was promised to get a replacement for the defective pan.
It is one month now after complaining, nothing happened yet, just wastage of my time purchasing this product. Never again!!
