bad customer service by call centre agents

last year in december i called the call centre to give me the amount to settle in full and i also wanted the account closed. the agent gave me the amount to settle and i asked if i should call back to close the account and she said i should not because once i pay the amount in full the account will be automatically closed so i did not. i settled the account but i did not know that an amount of R45 was added afterward as it was not brought to my attention and i thought the account was closed. i called the call centre yesterday and i spoke to a guy by the name of Robert from the Johannesburg branch and i asked him if i pay the amount immediately and i submit proof of payment, can the account be closed and will i get a paid up letter and he said yes. i paid yesterday and i submitted the proof of payment to ********** which was given to me by robert. i called yesterday afternoon again after submitting proof of payment and the lady said i should call back in 24 hours. i called again today and i spoke to 4 different call centre agents from the Durban branch. they gave me incorrect numbers for Johannesburg branch ********** / ********** . they said i should call the Johannesburg branch since i sent the proof of payment there. i could not get through, your stupid call centre agents from durban said i must keep on trying. do you honestly think i have the whole damn day to sit on the phone, and then they tell me the turn around time is 48hours even though i sent in proof of payment. i asked them to transfer me directly to the Johannesburg branch and they said its impossible. what kind of company are you that you cant maintain communication lines and its IMPOSSIBLE? so basically what is the truth because your dumb call centre agents are giving me different stories although i sent in proof of payment and they are gave me incorrect numbers? do your *********** call centre agents think its funny to make customers run around and give false info? implement some form of extra training for your DURBAN BRANCH BECAUSE IT SUCKS! I WILL NEVER PURCHASE ANYTHING FROM YOUR STORES EVER AGAIN AND I WILL ENCOURAGE OTHER PEOPLE NOT TO DO SO EITHER AFTER THIS EXPERIENCE.
