Poor service from Discovery

My husband and myself had a Covid Test on the 17 July 2021. I originally submitted my claim with the receipt I received from PathCare, the Test Results and my Discovery Health No. However Discovery kept requesting more information. They wanted the Invoice and how I paid for this Test, I sent them the Invoice from Pathcare and my Credit Card Statement which was the same as the receipt for R1700.00. In September I had new tests done in Italy from a laboratory called Bianalisi in Sestri Levante. The gave me a Fattura (Invoice) for E65.00 each and the Test results in Italian and English. I sent Discovery my passport duly stamped that I had traveled to Italy, my Turkish Plane ticket, the Fattura (Invoice) and the Test Results. Discovery wanted to know how I had paid for these Test. I told them in cash. Prior to my departure I completed a document that I was going overseas for 2 months so that I am covered while overseas. I also have gap cover. The documents were submitted for the first time in September 2021. I cannot tell you how many times I have phoned Discovery following up these claims. Discovery wants proof that I paid the Test in Italy with cash. I wrote to Bianalisi asking them how did I pay for my tests, they rep**** in contanti (cash). I sent Discovery the reply I received from Bianalisi, translated in English that I paid it in cash. Surely if they don't believe what I have said all they need to do is Google the translation. The latest is also that they cannot see when I submitted my claims. All they need to do is type in my Gmail address plus all the various reference Nos Very disappointed in the amount of time and energy I have spent following up these claims. I am happy to send you proof that I have submitted this information over and over again. Very disappointed by the poor service they provide to their clients.
