Client unrecognised by discovery systems

My name is Nontobeko Ruth Dlomo,I have not been identified in thier system whilst I’ve been paying for funeral since 2017. When I started calling Discovery in July in regards to this i was received by Phakama” which is an Agent for discovery, I asked them to rectify the problem yet they did not. I then however decided not pay till they sorted they issue out but the chose not, I then went to their Durban office to fix the issue however they promised to get back to me yet they did not even now. I got an email saying because I have not paid for 3 months my policy has been cancelled. With all said, can discovery pay back my money since 2017 till the date they decided to cancel my policy because they could not fix the problem caused by thier consultants. I provided my ID when I took this policy, and note that I had medical aid with Discovery and I still have a car insurance but they still have not fixed my money. I want my money please pay me.
