bad service

Hi have a complain with Cell C i have 4 telefone lines which is behind do to financial reasons but my one line *** which my son uses he decided to pay up his erase amoun due to te fact that he uses the phone fo work realised work so i contacted cell c to get the outstanding amount for his line *** which they sent me a sms to Good Day

*** January to March invoices *** - R***6972 - R945.77 Total - R1972.77

Contracts will be billed separately from next month.

Regards Cell C

that his amount due is R945.77 i made a paymet on the 20 of April paying R950 which would have made the account payed up i sent the proof of payment + asked then to activate the line need less to say it was not done so end of April came i did not pay April's premiums as i was still wating for feedback to why my line is not activate yet then this was there respons Amount due for cellphone number *** is R1,860.76.
