Cell C bad cusstomer service

Cell C played me so bad, I was in arrears by up to 21k and so I made arrangements with them to pay monthly until the account was paid up and they permanently deactivated my accoutn and they said it would be reactivated when i was finished paying, this happened end June so I started paying in July 25 and I was paying 1k am nonth until November where I made arrangement for 7k to be deducted on the 25th of November and was left with 6.6k which was deducted on the 21st of Dewcember and on the 22nd of December i went to Cell C in Umlazi Mega City Durban the lady contacted TPHD the company that deals with reactivating numbers and they asked for a paid up letter i then contacted MBD debt collectors for Cell C and they promised to send the letter however it was not done soon i was at this store from 11h30 to 14h30 still there was no answer the lady by the name of Sisanda said i must have an affidavit of which I had and ID also of which I had and the paid up letter.

Seeing that i was there long and on advise from Cell C they told me that maybe the paid up letter will come on the 27th I must come back then on the 27th I did not get the letter it only came on the 28th i quickly went to cELL c UMLAZI MEGA CITY only to find out that Sisanda was not at work and the lady I did not get her name was very rude to me there was no customer care from her side seeign that i paid all the money i was owing they did not care for me and so she went to call her manager and he did not help he told me the number has been given to someone and that person used a passport to get that number which is *** and so I assumed it was a foreigner and it was given on the 3rd of December and they said it would take 6 months so i was still within the 6 motnhs period, i don't understanding how can they just give my number to someone whilst i was still paying. To me Cell C has no care for the customers they only cae for what coems to them and if asked to go back to them I would never, they really did me bad, now i have to start with a new number.
