Extremely rude Customer Service

In the wake of the redfriday disaster,I was contacted by Greg Daniels from Silverton store who was particularly rude, in suggesting that it was my fault for not asking to see a manager on Friday to answer as to why the staff member said they did not receive the promotional stock. Is the staff member not qualified to assist customers on the floor? Did i not try to rectify the issue by laying a complaint on taking the matter up?Greg asked what i was wearing,what time i was in the store so that he could check on the cameras to see which staff member i spoke to(or to see if i was lying).He then said he will speak to his boss to see what he can do. He then called me back to say the cameras were facing d other way and that he cannot do anything else. What was the point then of d inquisition when all he says is there isnt anything he can do?Who then will take responsibility? or offer proof of them receiving the promo stock, and he refused to take ownership of why the staff member said they did not receive the promo stock. He said he cant check on the system to see d stock either. Checkline is refusing to take responsibility for the poor planning.What really being done to rectify d issue?
