NEW BUT NOWHERE

I subscribed to one of mrpmobile's offers in November 2015. I haven't as yet activated the contract but fully understand that I will still be billed the R129 pm as agreed. mrpmobile debited an amount of R175.40 from my account on the 15th December (and R99 on the 1st December) so I wanted to inquire how they got to these amounts, especially because nothing has been activated so nothing has been used. I have emailed a number of times but simply get no response whatsoever. I have sat on the phone and listened to their endless claims of glory and offers available but can't get to speak to anyone. Is this just another cell phone company with empty promises and NO after sales service!! So frustrating and such a waste of time. Be careful when subscribing to mrpmobile - understand exactly how they operate before signing anything!!
