Wrong billing

I had a 2 years contract with Mtn and they ended this February 2015.I lost my job November 2014 and couldn't pay for November to December and made arrangements for those months as I am still waiting for my uif.My line was cut in December 2014.To my surprise I was called by the cleaner 8f the flat that I used to stay and she says I have so many letters from Mtn only to find out they still busy billing me.<br> <br> My 24 months relationship passed and I am liable for the November 2014 to February bill.Aikhona mani Mtn stop robbing pple.
