Terrible Service From eBucks

I have received very poor service from eBucks. They made a mistake when calculating my October eBucks. I phoned the call centre and explained my problem. The lady who assisted me looked at my profile and agreed that a mistake had been made. I was told that eBucks would follow up with me and correct the mistake, but I received no feedback. After more than a week and after sending two emails asking for feedback, I eventually received an email, which gave me an explanation totally irrelevant to my query. It seems eBucks are either completely clueless, or just unwilling to help.
