Account closed

I opened my account sometime in 2013. I don't use my account frequently. I don't and haven't received any communication from Ackermans via email or sms. I went into a store today to check if my account was active for me to purchase. I was told that my account status is declined and closed. The cashier helped to contact the call centre. I spoke to a rude consultant from the call centre who refused to assist me. I checked using the 34413 as I was told to reapply. According to the return sms My account is still existent? The store manager said they can't assist or help as this must be dealt with at customer care. I have never received any communication from Ackermans that my account was going to be closed due to inactivity. Please reopen my account and reinstate it as it was. This is humiliating.
