<p>For the past 2years RMCS has been topping up airtime to my phone and only later on discovered that my number is no longer on Mtn prepaid but now a contract with RMCS.On a number of occasions I have tried to cancel this so called contract without success.As of now my sim is blocked and Mtn cannot cannot help me and I have been reffered to RMCS and all their contacts on their website is not working.I am now stuck with a blocked sim card which is frustraing me.I need help.Edgars cannot help as well even though this RMCS accesed our contacts through them.</p>
