RCS Store Cards Bad service

I'm very unhappy! Last month I did not receive my statement on time and when I actually did, I phoned and asked them to assist me with otems that is incorrect on my account.... They changed it after 3 days and did not want to help me with a new payment amount for the 1st of October. They just tell you sorry It will only be resolved new payment date. I'm very unhappy. Its now two weeks that I'm tryingbto unblock my website login. I spoke to 2 or 3 agents in regards to this as I want to pay my account for October!!!! One of them actually said she will send me an sms to create a new password and unblock my account. She never did. The other one did not want to help me as I've moved and my Residencial address is not the same as what is on the books. It's the 2nd and I could not pay my account as RCS does not want to help me to unblock and log in. My credit record has been affected negatively in regards to this. Very unhappy client first with my amount due that they don't want to help me and pull up their shoulders and then my profile is blocked. Want to log in to pay. Very unhappy.
