OMG that sounds like my experiences with car repair
I spent 5 hours at WalMart once, waiting for an OIL CHANGE
They kept telling me that it was almost ready, and I continued to shop and spent way too much money. THEN they did the same thing to me, my car was ready and they didn't let me know, I DID have my cell phone and they had the number
The very next day, my A/C died, so I don't recommend them at all. That cheap oil change ended up costing me $350 in WalMart, and $500 to fix my A/C
