Such bad service

I was given an amount to pay each month that I paid in full (even have on email and statements) Once I cancelled, I was told I had short paid so I must pay R200.00 I sent through email showing true amount. That was a month ago. Yesterday I received a phone call from their lawyers demanding the R200.00!! Disgusting DSTV...I think I will let you pay the legal costs just so I can show them the emails and statements.
