bad network shoddy service

Not happy with cell c lately. If it's not the slow reception that happened last week Wednesday and yesterday then it's the shoddy service I received. I purchased r30 airtime that went in its glory due to their slow network. and when I call the customer service line I get made like I'm the one to blame! I'm shocked that my airtime wasn't reimbursed! If it wasn't for my WhatsApp bundle I'd change next works NOW! I've been a cell c customer for 6 years now and I'm rather unimpressed with you guys!
