Amazon.de Referral fee payment issue - Pls help

Hi Warriors,
I really have no idea what else can I do. If you had experience with Amazon. de, kindly, please shed some light..

Well, the case is like this..I am not getting the cheque that they said they have sent. It has been dragged for about a year now (yes, you read that right! more than one year). Every time I report that I didn't receive the cheque, a customer service rep. will reply me that they will resend. And this process keep going on for a year. Each time I report that I didn't get the cheque, they will again reply that they will resend and the cheque never arrive.

And here's their latest reply:

I confirmed that the address given is correct and I'm receiving cheque from Amazon.co.uk to the same address. So, I just don't understand why it was undelivered.

I have tried the first option they now mentioned - to give an alternative address but it didn't work. As for the gift certificate, I wonder if I bought a physical product, how they can deliver to me if they can't even send a document (the cheque) to me.

I asked them if payment can be made via Paypal but being turned down. The referral fee might not be a big sum but it means a lot to me. I was thinking of asking them to send by courier service. But I am not sure what they will reply next and how much is left if they were to deduct the courier fee from my referral fee.

Or is it possible that they transfer the fund to my Amazon.co.uk or Amazon.com account instead? Anyone tried this?

Please Warriors...I really need some advice.

Thanks!
