International transfer

I'm so frustrated by capitec bank , have been receiving international transfers for years now , now the very same person sends money and I cannot receive it because the names are not full apparently and they cannot process the payment. I spoke to the sender and he even sent me proof of the names on the bank statement. Why is capitec not authorizing the payment instead returning it. It honestly does not make sense to me especially when the transfers has been an reoccurring thing. I'm so disappointed
