Harassment and Poor service

I am being harassed by the RCS call center agents with regards to my Edgars account. I have send emails and also called the Call center requesting a 6 month statement on my account because the figures dont add up . I was always told that i would get a response with 24 to 48 hours . Yet weeks have passed and there is no response. When we went to the Edgars stores they tell us that the new company is taking over and they cannot access the account until the new system is in place. Now you want to harass us for payment when the fault is also on ur side. Today i receive and email to say that i have not paid my account but no statement.
