Cancelled membership but now I have areas from where?

<p>I was a member of body life gym in Polokwane until I cancelled my membership last year in April because I was relocating to Pretoria.They stopped debiting my account.On the 22/06/2017 I received a call from MyburghRalenala attorneys telling me that I was handed over to them because I owe Body life R1000.00 something I was surprised because it was my first time to get a call from them and to my surprise my membership was R299.00 if I was owing them it should have been R3000.00 something until June 2017 their numbers are not adding up.I don't owe anything to the gym or their attorneys.Please clear my name.</p>
