Poor service from ABSA , being sent to multiple people at my own cost

On 16.11.22 I called ABSA to cancel my cheque and was told to call retensions and did do. I spoke to a lady , think her name is Busi who authenticated me and in the end said theres a block on my account ( instant loan block- I cleared the amount through the app whilst on the call) , attempted twice to cancel and could not assist me further. She said I should go to the bank, I rush to go there before 15:30. At the tellers in Tableview I was assisted by Lavern who said the accoubt cant be cancelled and she does not know why. A co-worker tried to assist but he said there was nothing they could do and they could not really advised as they had not encountered the situation. She gave me her number to call this morning for her to check for me. Ive called her twice to no avail and then called Retentions again and spoke to the same lady ( called at 09:10) and she said " did I speak to you yesterday"? I explained that I was at the branch then she said " as per our conversation yesterday , they were to call me so I can assist then to sort out the account". I told her that it felt like a confrontation and at that point I was furious because the consultant at the Bank should know that they should call retentions and should not be instructed by me.

Cancel my Cheque account or I will be moving banks
