Pathetic On-boarding Service from Bankmed

I recently visited the GP listed on the DSP network only for my claim to be rejected. Apparently my nominated Dr is one that i had seen 4 years ago and was automatically nominated, when I went onto this medical aid i was never asked to nominate a Dr nor did the app support you nominating the Dr, this was not communicated. I want bank med to refund me for my most recent visit, this is very poor service and I am going to take this to the Health Ombud, this is not fair, i have been paying my medical aid for 6 years now and in that space used the Dr twice, this is highly unfair and i will take this to social media and relevant platforms in order to get my claim through. Please call me urgently to sort this out.
