POOR POOR SERVICE

I have been a Cell C customer for few years. Never had an issue as their service were great. Recently I had trouble with double debit orders and requested my debit order to be cancelled and switch to manual payment as I struggled forever to get a refund. Eventually social media department assisted with this. BTW social media department is the only way things get done with Cell C. My one contract is due for upgrade, which I requested. Due to the manual payments not reflecting on same calendars day every month, they refusing to upgrade. Fine I am happy to cancel the contract then. Suddenly all 3 my contracts are being diverted to voice mail. Automatically for unknown reason. I am unable to receive calls and just get a missed call notification. Customer care cancelled all diverts, but problem still persists!!!!!!!. This is a breach of contract!. Stay away from cell c. Their is excuse is the same every time: LOADSHEDDING. Not my problem your towers are off, get backups!. This problem is during no loadshedding as well.
