pay up your account and you will be able to buy

My Edgars account was paid up to date after owing and paying under VVM debt collectors, the slip for the last payment I made instore showed a credit that I may use to spend on my account. Later in December, I went to CNA Mall @ Carnival to purchase and my account had been blocked permanently... If I wasn't good enough to be their customer anymore, then why did they lie and say I've got so much credit? And the lady at Edgard (Mall @ Carnival) did not even try to assist, I had to go and call their head office myself to find out the actual reason of the status of the account!!! Such unprofessionalism, and luring people with lies!
