Disgusted once more

After all my reviews FNB has responded stating I have to dispute debit orders and get refunded however I have done so and still have not received any refund for the double debits done on my account this is frustrating and I am unsatisfied having to constantly put them on this platform because they are inconsiderate and have no care for the customers . This is disappointing. I have sent an email stating that I have followed these procedures requested and my issue does not get resolved this has been going for months now I am totally disrupted by how they treat customers while this is all their mess
