Customer care and Legal pathetic service

I have always had a problem with cell c from the day I opened my account with them, the last straw is my account was over due by R390.81, SSDA called me to set up a payment arrangement, I received a letter from them as well. The payment was to be settled by the 25.08.2017, I however managed to make the payment on the 08.08.2017. I was then told to send POP to SSDA which I did it took a week before I heard anything and I had to call them they did not even have the courtesy to call me and update me. I eventually got an answer from SSDA AND WAS ADVISED TO CALL CELL C FOR FURTHER FEEDBACK AND UPDATE NOW THAT THE ACC IS UP TO DATE. I have being on the line for 3 hours landline and cell phone. I waited for 52 minutes before legal answered an just cut the call with no assistance. I call back again and have being transferred to every department just to be put on hold for legal again. the reason for all this my sim had being cancelled with no authorisation from me. NOT EVEN WHEN I WAS CONTACTED FOR PAYMENT DID ANY PERSON MENTION MY CONTRACT WILL BE CANCELLED. THIS IS TOTALLY RIDICULOUS WORSE SERVICE EVER RECIEVED..
