Poor customer service

I referred two members who signed up on 07/02/2015 and my details were provided for Adidas Totalsport vouchers. One of the members has enquired at least 4 times with the Little falls branch and was eventually advised to contact your head office directly. Not sure why this needs to be happen as the service failure lies on VA side and not the member. I then contacted your call centre and spoke to Nomvuyo Quwe who advised me the TAT was 3 days. This was on 09/03/2015. To date I have neither been contacted to provide feedback nor have I received the SMS regarding my vouchers. I have even sent a message on FB and the feedback I have received was that VA would investigate and get back to me. This is poor service and lack of accountability on both Little falls branch and head office. Why should the customer continuously follow up to get feedback. The feedback provided is insufficient and this is after a month and a half.
