PROOF OF PAYMENT WHEN THERE IS REF NUMBER

i PAID USING EFT ON 5th FEB. NOW THEY DO NOT WANT TO DELEVER MY GOODS BECAUSE THEY NEED PROOF OF PAYMENT, WHAT IS THE POINT OF HAVING A REFERENCE NUMBER IF I STILL NEDD TO SEND PROOF OF PAYMENT. THEY NEED TO GET A WAKE UP CALL AND MOVE ON WITH THE TIMES. AND NOW THEY DO NOT WANT MY BANK TO REVERSE PAYMENT, ******* MAN. I WANT MY MONEY BACK.
