National Tire & Battery [NTB] review: tampered with my battery post

Long story short I went in to have my routine oil change which I always go there and they did a point check and told me some things that needed to be fixed and said that I had a bad battery. Explain to them that I bought a battery for months ago it cannot be bad they stated it is. So a few days later after this event my truck started to stall as if the battery was acting up. I left my hood up and touch the posts on my battery to make sure they were still tight and noticed both post of the batteries were loose into the point that the screws were sticking out. So once I tighten the screws back up my truck started right up. I am very upset and disappointed on how they handled the situation of going to the extreme to loosen the bolts on my battery to make it seem that the battery was bad. If they did this to me how many other people you think they have done is to in order to make some money that's bad business what next brake lines disconnect to say that you need to replace it before your brake line bust. I was stranded for a while until I figure out what the problem was that my truck just started acting up out of the blue. Unsure if this have caused any damage to my 4 month old battery.
