4 years later still problems

Good day, <br> In 2011 I joined the gym a few months, later in 2012 due to circumstances myself and my sister moved to Cape Town. I am still living here and I still get phone calls from the gym. Everything was in order when we cancelled the contract. Now I am being threatened I will be given over to attorneys. I don't use the gym and I live in Cape Town, I don't understand how this is being brought up 3 years later. I haven't heard anything and now this is happening. Can someone please help me with this as I think this is unnecessary and everything was fine then now there is a problem. I will not be paying anything as I havent used the services of the gym for how many years and i immediately cancelled everything.<br> Thank you
