Worst service provider in the world due to *********** staff or out of date systems or both

2 weeks ago on Monday morning I received a call from Cell C stating that my account was in arrears, which it was not. I then sent through proof of payment which had been made 14 days prior to this call. I received a confirmation email stating that the payment had in fact been received and would be allocated to my account. Great! 3 days later I receive an sms stating that my account is in arrears, so I take my valuable time and call the call centre, only to be told that my account is in fact up to date. So this is sorted, haleluja. Ha, ha the joke is on me as last week Friday I receive an sms stating that my account is in arrears. Now I am angry beyond belief but again take my valuable time to call Cell C. Again I get told that my account is up to date and apologies for the frustration, the problem was being escalated, great! Ha, ha the joke is on me again as this morning I receive a call stating that my account is in arrears, this time the person who called can be very glad that the call got dropped before I could respond, but yet no call back. Please can somebody competent sort this out or Cell C please employ somebody competent, there are thousands of unemployed people who could use a job.
