Nothing New, Bad Service Discovery

Please can you educate your staff on your process. 05/04/2021 - I had 1st asked what information needs to be on the Invoice in order to process the claim. I was told ICD10 Code. When we had done what we needed and I submitted the Invoice. The claim was rejected because the ICD10 code was wrong and I need the procedure code instead. Then the date was wrong. I was advised that the payment would come from the "Special Payment from the Medical Savings" Okay, the lady said this was submitted and done. Then spoke to another lady to follow up she said again "Special Payment from the Medical Savings" - Okay. Waiting, waiting, its now the 7th June and today the guy send me the form to complete! Why can an agent not tell you all the information in 1 place and 1 time??? Why must I contact Discovery 7 times and numerous follows up to give me information that could have been given in April!!! And the sad thing is, I will get a call saying sorry but then the *********** staff will still not BE trained to give the correct information.
