Cell C bad services and data problems

I had a priblem with the data that I bought through cell c. Continuous connection problems. I have reported them on hello peter, they called me back and now want met to sign a APN APPLICATION form, this may vause unauthorized access to my device, usage of my data and open my system to be hacked by outsiders according to that document. Now they want me to sugn ot not to held them accoutable when it happen THIS IS NOW A LAUGHING MATTER!! I would not suggest cell c data to anyone. They are selling data to people NOT informumgvthem od their data service delivery problems. PLEASE BE WARNED NOT TO BUY ANY OF THEIR PRODUCTS!
