Payment not received from Discovery

I am hugely disappointed in Discovery. We have called numerous times to Discovery as payment has not been received from them for me to pay the doctors of whom operated on me. It has been over a month now. The first time payment didn't go through was because of a problem with their cheques then they said they would do an eft but the money didn't come through. The doctors are demanding payment and we paying out out of our own pockets.

Secondly, there has been a bit of a mess up with one of the doctors claiming twice of which Discovery said they would relook so that we can get the billing right. This has not been done, however the doctor is still demanding urgent payment.

As stated earlier I am hugely disappointed in Discovery's service for such a big company.
