cellc

I have been having problems with CelLC ce from day one. my problem with cell c is when i call to change my phone limits they seem to increase it from R50 then m told they only allowed to increase it by R200 then i get R250 for some stupid reason the call centre people have no idea of what what the increment is suppose to be. as a customer and as i pay the account myself i should should decide what i want. then i reported that my Sim card may be hacked because i have ridiculous amounts deducted from my bank account by cellc. the funny thing is i always switch off my phone data i use wifi most of my time all my apps are switched off. i get free data bundles every month and i receive a sms telling me when they getting finished and i ALWAYS recharge (buy more) no one seems to know where these items come from. i am very very unhappy at cell c and i want a solution where i can cancel my contract , freeze my contract till it ends just something. i cannot have a heart AK like this every second month with this provider i get problems i just WANT OUT!!! had the same problem in January where R1200 was debited and no could explain to me or give me full proof of my account poor customer care
