Disappointed customer

During the lock down period, i tried contacting the gym telephonically and via email. I had no response from fit 24. I had no choice but to put a stop order due to affordability at this time. I visited the gym today with the intention of canceling my stop order how ever i was told that i had to pay for the months i didn't pay and if i don't pay it will be taken further n effect my name. I don't think its fair that clients has to pay for a Service which we couldn't use and afford. Its not like i just decided to stop paying for my gym. I couldn't afford paying for a service i was not using. Please guys don't even think of getting urself in a company that shows no gratitude towards they clients
