Bad customer servicr

I am utterly disgusted in Clicks Pelican Park. I frequent this store as it is convenient and close to home. I purchased 2products but was incorrect. I lost my slip and went there to ask if they could assist me. I get home from work after 5 everyday but luckily they close at 6. I asked if they couldn't see the sale via my clicks card and I was told by the manager that the club card center closes at 4:30 and that they would have to call them. I asked if they could not assist any other way as I get home this time everyday. I have no use for the product and I dumped it in the bin in front of the manager. In no way was he willing to assist by even taking down my number to see what he could do. I understand that it was almost closing but it is still working hours. I would like to know what will be done about this as I am the loser now. I'm very irate at the moment!!!
