Disappointed promotion at Boxer

Absolutely disappointed by the promotion Boxer stores is running now. Shoprite and pick and pay are giving customers money back on the groceries we buy but boxer wants to give us a sim card and airtime for that sim card. I must now go and change my number because Boxer gives me airtime and I can only use it on that sim card which is theys. I use my number for my business and I will loose my customer if that sim xard they giving won't work. Is Boxer going to pay me for that business I loose. They not think about the community who support the store, they old people who don't know how all this works. They must give the customers back in money wise and not this sim card and airtime. Boxer is lost my business and my community business until they make better promotions like Shoprite.
