Vitality drive rewards

I recently added the Vitality drive for my car insurance with Discovery at an added cost obviously. I did that because of 'extra rewards/benefits' that were promised that I'm now not receiving. I send an email on the 19th June (mail reference *** asking why my km are not reflecting on the app as this will affect my plays on the game-board. They then manage to resolve the issue of km reflecting on the app but I was not awarded plays on the game-board. I email them again on the 21st June asking why am I not getting my plays. I then send them a screen shot of the issue on the 25th June since they seem not to want to give me my plays. They responded that the system department will investigate it. They then promised to allocate them the following week. On the 3rd July I emailed, again same issue. They responded that they will escalate the issue with the system department. Then by 10th July the plays have accumulated to 4, they decided to give me 2 instead, I then called them on the 11th July at 08:35 and spoke to Basetsana and she told me the same story we are sorry for the inconvenience our system department will investigate and allocate the plays next week. Today is next week and nothing. I think Discovery doesn't want us to get the maximum rewards that they promise because my chances are now high since I have more plays on the game-board so they are trying to give me bit by bit or think that I will be frustrated and give up. I'd rather cancel this thing than give up, I cant allow myself to be **********.
