CLAIM FROM MY SAVINGS

I made a cash payment for meds on the 29.12.2015, submitted a claim on the 06.01.2016, was told I have been sending incorrect documents, kept asking what to send,whenever I follwed up,was told the claim is not on the system. 24.02.2016 was told they will process my claim, I asked if they have my correct bank details, they sent me the old one, then sent me a form to complete with new bank acc, did so & sent back, when following up on the payment, they insisted they paid, only to find out they reimbursed that old bank acc. Then Michelle apologsed saying she didnt load the new bank details on receipt, but have done so & will be paid onthe 18.03.2016. On the 28.03.2016, i asked for proof of payment, only to be sent in the afternoon that the same old bank account was remibursed again, so how many times do I have to tell them Im not using that bank. Why did I have to waste my time taking the form they sent me to my bank to be stamped when they will still refund the bank they want to refund. Its almost April, this will be the fourth month since Im waiting for that claim. I am paying them +R3200.00 monthly but they take forver to reimburse a claim less than R800.00
