Lies and reversing Thank You points

I purchased on my cash Thank You Card yesterday 19/11 and noticed a balance of R10 TY points. My purchase three weeks ago stated a balance of R46 TY points of my slip. I went to La Lucia branch and a very nice and helpful lady assisted me. After 1 hour and 6 phone calls later she/we eventualy reached the Thank You Points Dept who informed me my points had been reversed because they expired. They said they send an SMS to inform me to use the points.They could not prove they did this! I have a smart phone and there is no record of any SMS and there is nothing on my till slips to indicate that points expire, whether promotional or not. We were then cut off... by this time the helpful lady and myself had enough. Why do Edgars give CUSTOMERS something with one hand and take it back with another? Surely the till slip should state that points must be used by a certain date. Please do not lie about SMSing when there is no record. Most disappointing and one would expect more from a company that brags on the website to investors but forgets about the CUSTOMER. Won't see me paying cash with my TY card for a long time. Can't trust you.
