I now owe R8000 for a poor mistake Cell C made!!

In April last year, a consultant from Sell direct contacted me to portable modem contract for R99 for 5gigs a month which seemed like a great deal!! So i signed up... and when i went to Cell C to collect my portable modem i was happy. The consultant failed to CAP my package, he did NOT mention that this 5gigs will be capped or not.. so i assumed it would cut off at 5gigs (Once i'd reached my limit) but it did not. I received an email stating that i owed R2000!! I immediately stopped using that modem!! I then went to Cell C and got a full on investigation going... they never called me back ever, i had to keep using my none Cell C line to call them every time as i was not on any other Cell C number or line. I had to keep going to the store to follow up.

Then eventually i stopped getting emails with the reminder to pay my Cell C account. Which i assumed by then tht it was resolved, I would try and call the customer care number but be on hold forever.

So by August i moved house and as i was packing i lost the reference number to my case. But i did not think anything as i thought this case was resolved.

Next thing in January this year or February (Cant remember exact month) i got a call from a debt collecting company stating that i now owe R8000!!!!!

I went to Cell C store to try see what they would say and they can not pick up my details on their system. They can not help me.. Their legal number keeps ringing... I am super annoyed and DEMAND an answer from CELL C. They need to help me, help with this. I feel this is extremely unfair and i feel this is *****!!
