Medical refund not paid (Contradicting feedback)

On the 10th December 2015, I sent the required documents to the claims department to get refund since I made a cash payment to a medical practice.<br> <br> On the 7th January 2016, I made a follow up call, the call center personnel informed me that the did not receive the documents and I was told that I should resend them so that I can be refunded.<br> <br> On the 19th February 2016, I made another follow up call since I have not received any feedback from the previous call, and no money was transferred to my account. The personnel whom I was talking to apologized for the matter, requested that I should resend the documents, and that the money will be transferred into by account before the end of that week.<br> <br> On the 7th March, I made another follow up call to bestmed and I was told that they cannot refund me as i do not have any funds left for 2015.<br> <br> This matter did not sit well with me since this was not the feedback i received from the previous info that was given to me. To me it looks like the matter was delayed on purpose, a delaying strategy, so that at a later stage I would be told that there are no funds.<br> <br> I would like the matter to be investigated & to have a factual feedback with proof.
