Walmart Supercenter: Tire & Lube Express

Arrived at 9am, had battery tested and was bad. It's under warranty so they tell us it could be up to two hours but can't give an exact time. My husband asks if he changes it out himself if they will still warranty it. They tell him yes, so he buys a cheap rachet set takes the old battery out and he goes in to get new battery to put in and they say they have to get manager to sign paper. I am sitting in van and watching all the cars come and go and they are working on all vehicles that came after us and my husband has had to repeatedly tell not ask anymore for them to get us the battery or fix tje battery. The time is now 10:49am!!!!!!Fuming ridiculous and mad!!!!!
