This Company is *****ing my airtime daily!!!

Well this weekend R20 a day has been deducted from my airtime and when i called CellC they provided me with the information i needed to figure out that i am being ****** of my airtime from a company called Smart Call!!! when i contacted the call centre the lady tells me im paying for something i joined in 2013 like what the hell?!?!?!?!?! but she cannot assist me further nor could she transfer me to her manager or supervisor because they are not in and she doesnt know when they will be in. so i email the company, got a response and gave them my cell phone number to investigate!!!!! They then questioned on how long i had the number which i didnt think anything of and provided them with that information which they then tell me that i am purchased some content that is R11020.00 in January 2011 but the lady at the call centre tells me i joined in January 2013??? These people are ***** and are ******** many people by the looks on the reports i have seen here and i did ask for proof for me joining whatever they are not even disclosing i have joined and i am still waiting. i will be taking this up to the small claims court and ensure this doesnt happen to other innocent people!!!!!
