No points allocated after large purchase

We purchased through Greenstone mall Customer service centre and paid EFT in May 2017. This was a large purchase and before purchasing we confirmed with Hayden Hill at the branch of the points will be allocated. He confirmed numerous times that a T5 account is no problem so the points will be allocated. After paying for purchase giving him all details like Dischem card number the points was never allocated and the battles begin we were sending him emails frequently phoning him and he was still confirming that the points will be allocated. After 5 months the points is still not allocated and he moved to head Office. The branch tried to assist but it seems without any luck. Hayden hill send us an email o sorry the points will not be allocated due to the new rule implemented in September. So Dischem your staff has let you down how can you advertise that with every purchase you will receive points on your card if this is not enforced by your staff???? According to the ombudsman there is no terms and conditions stating otherwise on your website! Your urgent response will be highly appreciated
