Bad service

I went to the bank to close my credit card account. I was told that I can do it telephonically and they put me through to the call centre. I was given a settlement value and was told that it is valid for 5 days. I wanted to pay at the bank with a card from another bank and they told me that they cannot do it. I made and eft payment. I called back two days later and was told that I still have an amount outstanding. I told them that that was the settlement value that was given to me and that is is valid for 5 days. They put me through to another person that said that they had no record was logged for a settlement value and that I had to pay the amount that was still outstanding. I paid the what they said what was still outstanding and had to call them again. It took me 7 days just to be able to close an account. I had to call back each time at my own cost to ensure that the account is being closed and to receive feedback. It is just frustrating that you have to go through so much effort to close an account and that it so easy for them to call you when they want business
