Poor customer service & communication

I would like to find out on how Cell C communicate with customers.

Late yesterday my WhatsApp msgs were not going through and I thought there was network problem. This morning my mom called in distress and her airtime was exhausted while she was still talking. I tried calling her and my calls where not going through

I phoned cell c wanting to know what was the fault with my phone. The consultant I spoke to told me my account was suspended because I am owing cell C R32.00 and she continued saying that there was an Sms that was sent to all Cell C customers stating that there would be an increase however it was not communicated to me that my account is going up by R11. On top of that Cell c has been receiving R400 from me and no one bothered to send an email or call to ask if I was aware of the price increase and that my account was in arrears of the R11 that Cell C increased my account with so that I can rectify my account. The only thing that happened my got suspended. The lady I spoke told me her supervisor was going to call me before 7:00 and I am still waiting.

If this the way Cell C is treating customers I want a network that would communicate well with me not cut my line for R11 I was not aware off.
