Cell C OVERBILLING

I reported an issue with overbilling and found absolute NO ONE would assist. I received a call on Monday 27th from a lady that confirmed tye overbilling and promised she'd refer the matter and get back to me. Well.... wouldn't you know it!! Haven't heard from Cell C since Monday morning. The disregard for clients and complaints os shocking! Been a very loyal client for about 10 years with an average of 3 contracts running. This is the thanks you get!!??? Shame on you, Cell C. Your business is not going to survive if THIS is the measure if your client interest.
