76 review: service & invalid gift card I purchased

I went to purchase gas with a gift card that I purchased back in December 2014 & I still had the receipt that I paid. The clerk working there said the gift card had anything on there & there was nothing she could do about it we have to talk to the manager & to leave the gift card I asked her for phone # to corporate office & she said she could not give it to me. There was a guy about the counter with her eating sunflower seeds with her not in uniform assisting customers & he continued telling us the gift card was no good cause we purchased it 2014 I then asked him for his name & she told me he does not work there & the clerk thst was working there was eating sunflower seeds with her fingers in her mouth & witness her grabbing money from customers touching money then touching customers hands not to mention not very clear english. I will no longer conduct business with 76 gas station & I always purchased gift cards from no longer u lost a good customer due to this bad service clerk & having unemployed people behind counter.
