CELL C's SH*T

I had a contract with cell c which i settled before the 24 month Term, I was not advised that after settling the account that 2 months later cell c would debit my account and that i would also forfeit all the data and minutes i had immediately after requesting that the account be converted to prepaid. I requested on numerous occasions a recording where a consultant advised me of this and no one bothered to send me those recording let alone explain why i should pay an amount i was not advised on. I then made a R50 arrangement which i kept however the acc got handed over to NUDEBT. I made an arrangement for payment with them, in the month of January 2018 i made a R250 payment which I mistakenly paid into the cell nedbank acc and sent the proof to NUDEBT to update Of which Sindisiwe rep**** and said ''We acknowledge your proof of payment Kindly be advised that your payment will be updated.". On the 7th of February. Again after recieving mails from NUDEBT and calls i sent another copy of the proof, of which Thandekile rep**** ''We acknowledge the receipt of the email Please be advised we have escalated the matter to cell c for payment confirmation, Please note will revert back to you with feedback.'' On the 20th of February. I paid the outstanding R109 on the 26th of February and requested a paid up letter via call and mail on the 1st and was advised ill get it on Monday the 5th which to now i have not received as NUDEBT says cell c has not updated the amount of R250 with them. I have tried getting hold of the cell c legal department but i keep holding with no answer. NUDEBT is also being rude with Thandekile going as far as calling me a ****! Bongani the ''Manager'' advised that the acc is on hold pending cell c letting them know of the payment as they had sent it to them for confirmation. Where does one get help when it comes to cell c, who does there job in that company, this is the exact reason why i chose to settle and port my number to Telkom mobile everyone seems to be *********** and unwilling to help, how do you explain a hold of over 20min. can someone allocate the funds so that I never ever have to deal with such incompetence from a network provider. I want my paid up letter!
