Payment done in a wrong account

I paid my account on the 26 February 2015 in a Vodacom store at SunnyPark, I then asked the guy who was helping me to make note so they don't push through the stop order this month of which I doubt that it was done. On the 1st March 2015 my phone service got \soft locked"when I called Vodacom they claimed that I did not pay my account and if I did it will eventually reflect on the system and the phone will be unlocked and if I had paid in Vodacom store it was supposed to reflect immediately. I called Vodacom every day since the day of suspension to check if they did receive my payment but they kept telling me same thing that I should email/ fax proof of payment \""of which I lost count of how many times I had done that! Until when I called again the consultant who was assisting picked up that the account is paid but the payment was done in a wrong account"
