STAY AWAY FROM MRP MOBILE

I CANCELLED CONTRACT WITH MRP MOBILE. YET, THEY EXPECT ME TO PAY WHILST I HAVE CANCELLED THE CONTRACT. THEY LOADED DATA THOUGH I COULD NOT USE AS IT WAS ON ROAMING AND THE SIM CARD WAS MIGRATED TO PREPAID. I NEVER USED THE DATA AND THE SIM CARD IS STILL ON ROAMING. WHY THEY DEMAND PAYMENT I DO NOT KNOW. ITS TIME I TAKE THIS MATTER TO CONSUMER AFFAIRS OR MEET WITH CEO OF CELL C OR GO TO HEAD OFFICE AND CAUSE CHAOS THERE. I HAVE HEARD ENOUGH!!!
