Failure to process claims

On the 26th of Jan I consulted with the optometrist and I had to pay the opt cash for the frame. On the 2nd of Feb i emailed my proof of payment together with the invoice. I followed up and was assured that I will be paid on the 12 Feb. on Friday the 12th still after my enquiry they still sent me an email confirming that the claim will be processed on the 12th. Today I called and I was kept on hold for a while and told a different tale, I am so annoyed that even the opt service fee is still not paid. The Banks should really reconsider this relationship because this is a really unacceptable and i wont be surprised if my doctor refuses to accept Bankmed and I will not be conformed to change doctors because of a med scheme that cannot pride itself in service delivery. this is not my first complaint with the scheme either.
