worst cell provider in sa

I upgraded my mobile contract about a year back and ever since I have had endless issues with the handset. It has never been in my position for more than 3 months straight as it continueosly breaks and when it goes for repairs I have to wait a month to get it back in worse condition than it went in with and still get billed the full amount while I dnt have a phone to use. I then need to spend hours calling call centres to track down updates of were my phone is due to cell c not. Being able to. Get back to during the agreed timeframes . This has been going on for far too long and I wish to please get out of this contract. Cell c keeps making decisions on my behalf without my consent like da latest decision to send a new phone out to me dat by the way had to be sent back for the exact same issue
