Empty promises and pathetic "service"

I submitted a claim for an amount that would need to be refunded to me for a GP consultation in July/August 2017.

Made the call and was informed the refund would be processed by early September 2017. By mid September no refund received and when I called to follow I was informed the banking details on THEIR system is incorrect so it was processed to an incorrect account number. To which I had to provide proof of banking details at my expense.

A few days pass and no word , I then have to follow up to find out all they did was update details but not reprocess the claim.

Move on to today 26/10/2017 and I was promised payment 3 days after the 20/10/2017 and still nothing. This after previously being promised the same for payment 3 days after 14/10/2017. Today again I spoke to a Rebecca today who promised a Thendela Hlongwane (manager) would return a call to deal with this but NOTHING? Call ref ********** 43

Pathetic!!! As they do not EVER make the mistake of missing a deduction but cannot do as they are supposed to or as the say they will. All the while the funds due for claim refunds accrue interest in their account but the refunds do not accrue any?

They also have no formal complaint line, mail box or anything as I take it this is how they do not operate. If only I had a choice to move.
