POOR CUSTOMER SERVICE

I am very disappointed in the service I receive from Discovery Vitality. I made a healthy gear purchase on 28-2-2015 at Totalsports Sandton for R1808. I noticed that I did not receive my cashback on 9-09-2015 for the healthy gear purchase I made. I logged a query with Vitality on the 10-03-2015 whereby I also sent them the proof of my purchase and I was promised that the matter was escalated and they would get back to me. I received several call backs during the first week I logged the query from a consultant named Sheray who updated me on the progress of the query and said that they are still busy investigating and will get back to me. I received my cashback for March month paid into my account yesterday and the healthy gear cashback was still not included. I called the call centre again today at 12:55 and spoke to Lesego who said that they are still busy investigating my query and they will get back to me as soon as its resolved. It is just unacceptable for a big organisation like Discovery to drag a simple query for so long. If that is what they call customer service then surely they shouldn't be ranked as one of the top service providers in SA. VERY DISAPPOINTED!!!!!
