*****!!! *****!!! *****!!!

I have never in all my life seen such utter bad service and lies from any service provider. What a bunch of ******!! False sales and lies ALL THE WAY! Ever since I have agreed to a mobile contract with MRP Group, I have been done in from the get go. I got told the STK phone was 4G - LIE!!! I got told the STK was an LTE phone - BIG LIE! The thing has so many glitches and is slower than a Windows 98 PC! I got told it has 8G memory - LIES! But the best part and the best lie they got away with was the "it's only R149 per month"! I agreed to the R149 pm deal. 2 weeks after I received the phone, I got a call to say the contract has no limits and I need to set my own, after I got **** to, with the contract is set to R100 airtime, 100mb data and 50 sms's. I set the limits nonetheless. I got told my contract will only be debited from 1 October 2017, LIES!! It got debited on 1 September! First month in I paid R199 - this was supposed to be the first installment amount to activate the sim etc. I had not problem, apart from the fact that I was debited a month earlier than the initial date that I got told I would be debited on. Luckily I had those funds in my account. Second month around, I am now expecting to pay the R149 as agreed to, especially since I set my limits and did not go over the limits I gottold was supposedly on the contract even before I received the call advising that the contract had no limits. I was under the impression that I had only R100 worth of airtime, 100mb data and 50 smss and once I had reached those limits, I switched my data sim to my Vodacom sim. Second month I received a call advising that they will be debiting R295-49. When I asked how on earth they got to that amount or why it is not the agreed R149 pm, I g ottold someone will phone me. No one ever phoned and my account was just debited. So then last month I made sure to phone and ask what ridiculous installment will now be debited from my account, I was advised it will be an amount of R151-62. Again I asked how this is possible when I specifically agreed to a contract costing no more than R149 pm?? Again no explanation could be given, but I was assured that that is the maximum amount they will ever debit. LIES!!! Now I receive an sms advising that my account will be debited with R187-38. I WANT TO KNOW HOW IT IS POSSIBLE TO DEBIT AMOUNTS JUST AS YOU PLEASE WHEN I SPECIFICALLY AGREED TO ONLY R149 PER MONTH ON A SET LIMIT CONTRACT??? I WANT EXPLANATIONS AND I WANT THIS SORTED OUT WITH IMMEDIATE EFFECT!!!
