MRP Mobile terrible service, they **** people

I took a contract more than 2 years ago. It ended this February 2020. Since the beginning of a contract, they never phoned me or email me. June 2020 they started phoning me telling that I am behind with payments since there was no money coming into my account because of lockdown. I asked when is it ending this contract. They said February 2020. I then asked then why are they phoning me and they told me I was suppose to phone them and tell them that I am not continuing with this contract which was strange because they did not tell me that I will have to phone and did not send any email to tell me that. They waited for me to owe something then phone. They told that I can still an email of cancellation and when I did they declined it saying they will only do that when I have paid them. This is so unfair. That number has been inactive since last year. Can't they see that I was not even using their services.
