Easypay and Norlam attorneys I need my money

I made a payment to Norlam Attorneys on the 25th June and provided proof of payment however till today the money is still not allocated becuase they claim they didnt receive the money. I checked numerous time with my bank and the payment is sucesfull. Easypay its difficult to get hold of them and Norlam attorneys is not willing to invesitigate on their side,
