Bul**** at builders

I went to builders this morning to get a gas cylinder with gas after I had called the call center yesterday and was given prices and availability,upon my arrival at builders express Robindale I was told to get such I must buy a Gold air heater I refused and told them that is not what was said to me and requested them to show me where it was written and the manager failed to produce such.when I told the manager I will not leave with getting the gas heater she asked some men in the store to throw me out of the store and I told them I will beat them up....an hour later of fighting,cursing and threats I was finally sold a gas cylinder filled with gas
