overcharged

This refers to a complaint i lodged earlier. I was contacted by Cell C (Patrick Mphuti) regarding my initial complaint on 23-04-2015 who explained that I was correctly billed due to the fact that I had exhausted my midnite data although I still had my 5gig data which is what i signed up for. This explanation is in contradiction with what is on the company website. I emailed the person back with a copy of what is on their company website
