Still ignoring the CPA and not responding even though an undertaking was made on my previous post

I complained last week about not adhering to the CPA, I was promised that this would be resolved, all I got was a call from a RUDE center agent telling me that they cannot help and will call in two days. It's now 5 days, furthermore, IAckermans is BOUND to the CPA and it is irrelevant what your in store policies are. You are blatantly ignoring an act which overrides any store policy that you may have. I have rights as a consumer and I want to exercise them, why is it that Ackermans feels that they are above the law. Unfortunately I am not one of those people that "will go away" - I want this resolved and am well within my rights as afforded to me by the consumer protection act.
