Vodacom and FNB giving me the run around

Hi, My name is Matsie , I had a billing query with Vodacom and was advised by Vodacom agent to deposit payment onto their account using the FNB App Public Recipient platform to make payment. I then paid R544 on the 2nd May to Vodacom PTY LTD on the FNB app, i sent Vodacom the proof of payment and they came back saying they cant find the payment on their side as the account number on the FNB App Public Recipient is not their account number and i have to contact my bank FNB and they must sort it out. I contacted FNB spoke to Bongekile to provide me with the merchants details so that i can contact them under account number *** so that i can try and get them to reverse the money on their side and was advised that they cant give out the details i was supposed to check the account number before making the deposit which is ludicrous because the account number is not available on the app. FNB is supposed to verify the public recipients details before loading them on the APP for the public. Now Vodacom has sent me back to FNB and FNB is sending me back to Vodacom however Vodacom cant assist and FNB my bank cant reverse the money back into my account. I need the telephone number linked to the Vodacom account number on the FNB app or my money back into my account.
