A loosing battle - Trying to get my money back!

In Dec-14 i entered my threshold benefit. My wife contacted Discovery about purchasing a BP Machine & it was confirmed that they would cover this device. 05-Dec-14 i purchased a BP Machine from the leading supplier of Health Care Equipment to the industry. After submitting my claim, my claim was rejected over and over again. Each time, the reason given was different.Finally I was told that my claim was rejected because there was no practice number. I explained to them that I was not informed about this. The recordings were pulled up and 3 months later, Discovery concede that there were in the wrong and will pay out my claim. To date, no payment has been made. I have all the reference numbers. Last 3:<br> - 24 Feb 15 R/N:***<br> -17 Feb 15 R/N:*** <br> -05 Feb 15 R/N:***
