FRUSTRATED AND ANGRY BY THE SERVICE FROM MRP MOBILE, IT'S APPALLLING

I'm highly disappointed and angry with MRP Mobile, i had a contract with them and requested that can they please cancel the contract. I even went to Alberton Mr Price store to request for them to close my account. And they told me that i owed around R220 which i paid on Saturday via EFT and on Monday, sent them an email confirming that i have made a payment can they close the account. Only to be called by a consultant telling me that i owe R139 on the contract as a result it won't be close. I was soo livid cos firstly i request that they close my account telephonically, which they didn't. Still went to Alberton Store thinking maybe something different will happen but nothing. Also when you go to the shop they still put you on call and speak to an agent. I'm soo angry because it's been more than a year i have not been using thier service yet they expect me to pay every month. I've been paying so that my credit can be clear but now they have really pushed me over the edge. I'M SOOO FRUSTRATED WITH THIER SERVICE AND JUDGING BY THE REVIEWS THAT I HAVE READ, THEY ARE NOT PREPARED TO IMPROVE. I soo wish that someone could take this up with them.
