Lost momentum for customer service

As a cricket loving family, the Momentum Multiply reward of discounted cricket tickets, both domestic and international, has been one of the main reasons for me to remain a Multiply member. As Platinum members we receive 70% discount on ODD T20 and 40% on International Series (ODI, T20 and test matches), as per the Momentum Multiply T&C's. However on Monday, 26 November, when the ticket sales opened for the much anticipated series against Pakistan, there was no Momentum Multiply logon button on the Ticketpro website. I immediately contacted your call centre on Monday at 11h53 and was assisted by Sakhiwe, who logged the call and promised to respond to my query. I phoned again at 17h09 and was assisted by Lebogang - still no response. I also made use of your online chat - the first agent informed me that this reward was not for international matches and closed my chat. The second agent closed my chat without assisting due to "limited access" and asked me to contact the call centre. I sent an e-mail to ********** on Tuesday, 27 Nov at 08h59 - no response after 48 hours - not even an acknowledgement of my query. I again phoned the call centre on Wednesday 28 November at 09h41 and was assisted by Nathaniel. He promised to call me back by the end of the day to give me a status update......still waiting for the call back Nathaniel!
