bad customer service

I am so irate and disgusted in the level of service I am receiving. I sent through a claim on the 24 july for antenatal classes I attended in january, I paid cash amounting to R800.00 for the classes. The sister that gave the classes did not have a practice number amd was busy registering at the time and advised as soon as she gets the number she will then send an invoice. She only sent me the invoice on the 24 july. I sent this to bankmed with a motivation as to what happened and why there was a delay. This is not my fault that it took so long I want my refund as this was not my problem. I need this to be sorted out a.s.a.p. I spoke to f mapukela at client service who advised everything is in order however I received a statement today to say it was denied again.
