On March 3rd 2021 i went to the pep boys at 7440 W Peoria Ave in Peoria Az, my fuel gage was not working. I had an engine diagnostic check done it was determined i needed a fuel pump. I believe i was over charged for the labor conducted the amount was 772.42 total just to install. I had the work done because i needed it done in order to register my vehicle along with passing the smog test. Three days later on 3-6-21 after getting off of work i started my car and the gage was not working again, i went straight to the pep boys and explained what had happen.The manager at the time asked me when could i bring it back in to be looked at i told him the following week after i completed my work week. On 3-10-21 i returned to pep boys to fix the problem . They explained to me that they needed to drop my fuel tank to check if there were other issues keeping the pump from performing at a price of $359.32 and replace the fuel tank for $617.55 i told them i would think about it considering i just spent $772.42 for the pump with no results. I asked is it possible to have gotten a bad pump they said yes.So i asked if they could check that out ( install another pump) they said they would I watched from the waiting room next to the bay while they drove it in.I never observed a new pump being switched out.They pulled the car back around front and handed me the keys and said that it was good.They never gave me new paperwork, i got in my car started it and the gage was still not working so they lied to me about the work performed.Because the gage was still not working i was not sure how much gas was in the vehicle so i went across the street to a service station and attempted to put gas in, and was enable to put gas in the car for whatever reason the gas overflowed out of the car as if i had a full tank of gas.Even before the car was taken in i still was able to put gas in with gage not working now i can't even do that.I don't believe i was treated in a fair professional manner by the store and they made my situation worse than it was before, now i have to spend more money to correct what was a simple fix i feel it's not right
