Epson Cashback **** continues

Acquired a Epson L3110 Printer scanner Registered for Cashback Promotion Acknowledged by Epson and I was given the portal info to check status of the cashback The next day a request came for Branch Code and Sort Code, I am to do this via the Portal Unable to open Portal, incorrect user/password. On "Contact us" lodged my problem. New password given with at least 10 languages. (Not Swahili though). Twice I was given a new Password. My feeling is that die Cashback Promotion is ca ****. The buyer have so much difiiculty that he lets it go and forfeit the cashback. That reads **** **** in any language ****. If my problem is not rectified, one will have to look at other routes of solving it. This is the worst business I have come across in my entire life.
