Error claims

I am deeply concern about the work ethic of Discovery Claims section. The reason being that I paid cash to a service provider 12 June 2020 where after I submitted the online. On the 20 June 2020, I checked whether the claim was processed and discovered that the same amount was paid to the service provider. Thus, I paid double for the service delivered. I first tried to communicate via Discovery’s ‘chat’ which rep**** to me with inappropriate and unsatisfying questions. I then phoned the help Desk who assured me that they have already paid the amount back 16 June 2020 confirming with an email that it was paid in an incorrect person’s bank account. I then phone them back and the help desk indicated that it was a typo error and assured me that it took 3 days to show on my bank account. Strange that is was already 4 days after they supposedly paid the amount back! At this stage, I am waiting for Monday 22 June to see whether the amount is paid back. I am just wondering if a person is really ill, he would not have the strength to scrutinise such error in detail. My advice to fellow members to report these irregularities.
