Mrp mobile worst service evwr

I am trying to cancel my contract now sinxe Sept 2020. I called them and was told i need to send a mail i did. They respond back and now they claimed they have never receiced one if about 60 yes sixty mails send. The one lady advised me they do not have a complaints dept, manager, supervisor or CEO. The other one told me i need to pqy R250 first to cancel, i mean why i gavw thwm notice after 2 years and they are still deducting. So they owe me money. They offered me n new contract th3 guy was very blunt and juat hanged up the phone without greeting. When i told them I will request Hellopeter she asked me who is hellopeter. Really this is rhe worst service ever as i qm not using it as i did it for one of my boys who doesnt know.where the phone or the sim is. Why should i keep on paying and dont use it and how did they only receive the one email bit 60 others they cannot confirm or deny receiving it
