FNB eBucks Sucks

Who has ever struggled with FNB eBucks. Every month must I check the credit I got from eBucks. Op 30 September 2021 I fill up with diesel at an Engen garage. This transaction is simply ignored. In November, two transactions were ignored. I log a query on FNB's website and specifically ask that they must not contact me per phone as this is a business phone. I specifically request that I be contacted by email. The same day I got a call from eBucks and I explained that they should contact me by email. An SMS was sent saying they do not have an email address. This after a complaint number was issued to me, by email, by FNB. Needless to say, I've never heard of FNB again.
