Trying to get my money back from a claim

I sent Discovery proof of an account i paid myself on 25/01/2018. I am still waiting for them to Refund my claim expenses incurred.They look for every excuse under the sun why the claim still has not been paid. Everytime you call the agents repeat same story with no resolution.As for the CRM Rozanne Govender still waiting for feedback. Discovery are the greatest at taking money. However when they owe you money its like pulling blood from a stone. Their agents are the worst with the acknowledgement of how I feel.......................You don't know your bank account is not short R1966. As for their assessors in claims I did not **** anyone I made for a Sonar so stop rejecting the claim and pay me back. I had Hospital Auth numbers for that day this was done for my son at the hospital. Stop acting dumb like you'll don't understand or have all codes on hand, please just reimburse ME.
