Cell c LEGAL IS A JOKE!!

I have been on contract with cell c for over 6 years. In January I was told my phone numbers have been cut off due to none-payment that I was not aware of. On 2 June I tried contacting them NUMEROUS times to settle the debt and I still have had NO RESPONSE FROM THEM! I am absolutely disgusted at the level of disrespect when I have emailed and called multiple times trying to pay it off so my contract can continue. I absolutely refuse to pay a cent more interest for the new month as it is ON THEM FOR NOT CONTACTING ME BACK!
