Very difficult to try and close your credit card

On 12 March my husband phoned the Standard bank credit card division and requested a settlement amount to close the credit card. They informed us that they will phone us back with the amount - they never did.<br> <br> On 17 March 2015 we phoned the Standard Bank Blue Bean credit card division again and requested again a settlement amount to pay off our credit card facility to close the credit card. The amount was then given to us and we paid the amount off the very same day - Call reference ***. We then destroyed our card.<br> <br> A few weeks later we started to get sms's from the bank informing us that we still owe money on the account.<br> <br> My husband phoned them to enquire as to what the problem is because this account is closed. They then said the lady made a fault with the interest and we still owe some money, etc. etc. They said they would come back to us - they never did.<br> <br> We then decided to lodged a formal complaint on 4 May 2015 via e-mail. We were informed on 6 May that the dispute is now open and we must allow them until 12 May for investigation and resolution. It is 1 June today and we are still waiting... and still getting sms's from the bank. Please help!
