Poor communication and zero confidentiality

Good day all So I filled in a form to cancel my account in October 2019. Then a colleague of mine received a phone call from Mr. Price in early December stating that I must pay my account which is in arreas after I paid it up in October before I closed the account. What is alarming and upsetting is that Mr. Price contacted someone else for my account.How they got her number? I dont know. Why my account was not closed as i requested in October this year? I do not know and then I paid the amount which esculated on my account on Thursday 12th December after getting a threatening message (not even send to my number,but to my colleagues number) from Mr. Price that the credit Bureau was informed of my account being in arreas, the account that was suppose to be closed in October.After making the payment I phoned customer service who put me through to accounts whom I then asked to close the account and email confirmation to me, which I never received by the way. Only to go into Mr. Price Canal Walk yesterday to check if the account is closed and to my surprise it still wasn't closed. I phoned customer service again this morning requesting it to be cancelled and what happened? A message was send to my colleague again to state that I requested a cancelation on my account. Well at least I received feedback, but after giving my number to them so many times they still send my confidential details to my colleague. This is unacceptable, also shaming my name for no reason at the credit Bureau and people I know. I am disgusted by the lack of confidentiality of Mr. Price. For all the years that I have been an account holder of Mr.Price I will never support them again. They are making my holidays miserable.
