AutoZone Bushbuckridge Customer Service

My sister and I went there looking for assistance with a car battery. I personally asked if the store worked with car batteries and the cashier said "yes, we do". We decided we wanted to buy the car battery and he asked if we had a spanner. Which was an unusual ask and I thought maybe it meant each car uses its own. When I took out the tool bag from the car we were told we have to remove the car battery ourselves unless we ask them to do it. This was surprising to us because when I first asked if they work with car batteries and they said that they do, nothing was mentioned of the customer who has no mechanical knowledge/experience at all, removing the car battery themselves. When I questioned this, only then does the cashier say that they are a retail store and it is not their job to change the battery. Such a bad service and poor communication received at AutoZone Bushbuckridge. It is truly disappointing.
