Replaced battery at sears, now car won't start

Did it run before you took it to sears?

Yep it was running. The battery was dead so I jumped it and went immediatly to replace it. I stopped at Sears because it was on my way.
Haven't had any other issues.

The first battery didn't work? I haven't had this experience before, but the sears guy acted as though that was normal; got a second NEW battery hooked it up, also put my old battery on their charger.

I had my back turned for a few minutes at their computer/getting paperwork at this time.

With new Die Hard my Car cranks but won't start. Oh and they said they were too busy to help me. I asked for a different battery, but they said no. NO? And then they dissapeared working so so very hard!

I called my mechanic and he told me what was happening was totally wrong. He was also too busy to come over, only thing he could think was to tow it over to him.

I just couldn't see spending over $200. When it had to be something simple. So I checked everything I could get at. This is interesting because All the employees at this Sears auto place are ignoring me, and I'm borrowing their tools, I also went and checked the old battery, (which had charged fully by this time) took it off the charger (employees only area) hooked it up, (it cranked but didn't start (and the battery lost the charge quickly). I Put the NEW die hard in, again. NADA.

I had stopped to purchase a new battery at 2 O'Clock, gave up and called a taxi at 6 PM after pushing it into a parking spot (I locked it and kept my keys). I took a taxi home.

Next day when I called them the man on the phone told me they had "been working on my car and determined the problem was the ignition". My response was (LOL) "without keys"?

Then he asks me for the keys so they can diagnose the problem! LOLOL

So I'm a bit stuck, mechanics is not my preferred area of expertise. And coming up with the proper question so I can solve this has now changed:
What did the Sear's guy do that involves the ignition and would cause the car not to start?

Well I dont want to blame someone when somtimes things just happen, now they may have pulled a wire out of place or a wire was weak and diddent like to be moved or at worst they left the key on and hooked the batt up backwards & smoked the ign module, I would start with the wires by the batt maybe one is unpluged, check everywhere for unpluged wires. Hope I helped.

That's what I was thinking too--The 1st thing I checked was the wiring, it seemed logical to me that a wire was accidently pulled out of place or something like that.

And I feel the same way as far as blame-- I would not assume to assign blame on anyone, and accidents happen, no big deal.

I did not consider they might have put the battery in backwards. That would be a big WOOP**** for an ACE prof. Wouldn't it! Can't believe I didnt think of that! It is a funny thot isn't it? An AssBackward Battery Smokin!
Professional embarrassment (taking one-self too seriously) would make sense & explain everything that happened.

Thanks. I needed a new direction to explore. Appreciate your time and thot's.
