BAD Customer treatment and RUDE Call centre agents

I have been calling the call centre since June this year trying to get my account closed.everytime I call I was being told that it will take 6 weeks,i called a few times after that and I am still being told the same thing, the call centre agent are very rude and do not know how to speak with clients , I was even told by Romario that I was being ridiculous and Charlene told me that I was being dramatic ,all for wanting my account to be closed ,below is the list of the people that I spoke with everytime I called the call centre and honestly speaking they all couldn't careless ,don't know if it was because they don't have my business anymore. Mpoyetsi - logged a call wih him to close my account and he never send the request to the closure department. Romario - Didn't even have interest on my query and told me to chill out Kaashif - team leader that was going to call me in two hours and he never did . Charlene - told me to chill out and drop the phone while I was still talking to her . Nosiphiwo - said that the account will be closed in 48 hours . Lerato - Advised that she will put block to my account .
