Medscheme Polmed poor service

I received a sms with wrong banking details, demanding payment for a membership portion to a pharmacy. Four (4) phone calls later and no one can tell me what the fees are for. My membership got suspended after I was told that if I pay the money, the suspension will be lifted on the first. After a phone call yesterday, I was told the suspension will take another week to be lifted. Polmed demanded payment for a claim in March 2020. In August they decided I owe them money. The first person I spoke to, put the phone down in my ear in August, when I asked which claim this money relates to. Two more people working for polmed told me they can not tell me what the outstanding money was for. the 4th person to assist me, left me on hold for half an hour and put the phone down in my ear. Plomed refuse to provide details of the money they insisted I owe them and suspended my membership but they don't know what for. Sending a paying member an sms without details is not acceptable. They won't pay a claim like that, but they expect members to pay them without know what it's for.
