I haven't received my Mrewards from Makro and the sales person has not assisted me.

I bought a washing machine on Thursday from Makro Springfield and was promised by the sales person Mxolisi Yaka that I will receive my rewards in 48 hours. I called Mxolisi on Saturday to enquire and he just nonchalantly said I must just wait without even bothering to check with his head office. I called him again this morning and asked him to enquire and call me back which he promised to do but didn't. I had a problem with the hose fittings for the washing machine and he couldn't assist me or atleast find someone to assist me. I am very disappointed with this service or lack theerof. To me it seems as if it was only about the sale and no after sales service.
