RCS USELESS SERVICE

I have been trying to reset my Pick n Pay Smart Shopper Account pin for over 2 hours this morning. RCS is utterly and absolutely useless. I have been told several times to accept the SMS, but surprise, surprise - no SMS comes through. Apparently once I accept the SMS they will call me back to assist. This cannot be done if the SMS doesn't come through and subsequently no call back??????? I was also advised to utilise the USSD system to change the PIN. THIS DOESN;T WORK EITHER. MESSAGE RECEIVED IS "UNFORTUNATELY WE HAVE BEEN UNABLE TO CREATE YOUR PICK N PAY STORE CARD PIN. PLEASE CALL US ON *** FOR MORE INFORMATION". NONE OF THE CONSULTANTS HAVE BEEN ABLE TO RESOLVE THIS ISSUE. I WAS ALSO TOLD THAT THEY CAN'T ASSIST ME IF I UTILISE A CONTRACT PHONE, IT NEEDS TO BE A PREPAID PHONE. THIS IS BULL****, WHAT DIFFERENCE DOES THIS MAKE?????????????????

I AM TOTALLY DISGUSTED WITH THE LACK OF ASSISTANCE RECEIVED FROM RCS.AND RECOMMEND YOU NOT TO UTILISE THEIR SERVICES. HOW DIFFICULT IS IT TO RESET A PIN???????????????????/
