Appaling service

I sent money via Malvern Spar yesterday ,sum of R3000. When the receiver went to draw the moneythe pin said its incorrect. Upon seeing the slip I realized that I had made a mistake with the last digit of my phone number. I went to spar this morning to reset the pin but they said I need to call the standard bank instant money on ***. When i spoke to the consultant he advised me to go back to spar and ask the supervisor to fix my cell phone so that we could change the pin. The supervisor there at Spar Malvern Jules street by the name of Lungile flat out told me that they cannot use their phones at spar to speak to the standard bank call centre. I had to buy airtime for her to speak to standard bank . What an appalling thing to do . Standard has now advised me that it will take up too 24 hours to fix the number. I explained to them that the receiver needs the funds as in yesterday .I asked them to reverse the transaction then but they said it cannot be done unless they fix the number on their side . Can someone help me to speed this up as the funds are needed urgently please. As to the appalling service that I received from Lungile at Spar I will definitely not be using their service anymore.
