Covid 19 cashflow relief owes me money!

I took out the Covid relief loan which covered April, May and June. After which I was contacted offering me an additional loan for two more months. I was told it would cover March and July (I was told March wasn't paid, but actually debit orders went off my cheque account). So the additional amount reflected, then disappeared on my Covid account, and end of July, my debit orders went off as normal on my Cheque account. After that, the covid money reflected again. So in other words, I personally paid for March and July, yet I owe money to the covid loan.

So I phoned all departments for the last three weeks, to get reimbursed the amount for the two months that were supposed to be covered by the loan, which I paid out of my own account. Every single time I'm told FNB can't contact the covid people directly, but only by email. My patience is running very thin... I'm told each time it will take a day or two, then another week goes by and no money and no one contacts me. I am fed up, who do I need to talk to to get refunded, otherwise I will be forced to take this matter much further!
