Unallocated deposit after a successful card payment

Unallocated deposit after a successful card payment and terrible support. EasyEquities says my transaction history from FNB are “invalid”, even though my name, account number, date, amount and their merchant name all appear clearly. Their payment gateway debited my FNB account but failed to allocate the funds, yet support keeps repeating the same script instead of actually helping, gives no real explanation why an FNB-issued document is “invalid”, and refuses to escalate or engage with the bank to resolve the issue. I feel completely let down by the support line and left in limbo with my money stuck.
