Seven Auto Sales HP

If I could leave not one single star - I would. I came here over the summer a couple times based on a community review. She said they were fair priced and good. Being a single mom of 5 on a limited budget, fair priced was what I needed. I would soon learn fair priced meant cheap work.
First I had my brakes done. The light keeps going off every 3 miles to tell me I need service. At first I thought they just didn't reset the light and let it go.
About a month later, my battery die. Since this was summer and I hadn't left anything on, I thought this was odd. I took it back to them to have the battery and alternator checked. They said both were fine.
When I needed my radiator replaced, I again went to Seven Auto. The mechanic did tell me that the core support had rust to the point where the radiator could no longer be attached. The mechanic then said he would affix the radiator to my vehicle using an alternative method of support.
Now, my knowledge of auto mechanics is extremely limited. I never even thought to look and see how the mechanic affixed the radiator to ensure it had support.
Fast forward 3 months later....
My brakes have had to be repaired again. The battery did need replacing. And the method this crack auto "mechanic" used to affix my radiator?? WIRE! He put wire through the fins (new term I just learned) of the radiator so it made like this neat little saw that created a HUGE GAPING HOLE in my radiator. So now the radiator needs to be fixed again and they want to charge me for them actually affixing the radiator like they should have the first time! Had this been done the first time - I would have gladly paid for it. Now to correct their mistake I don't feel as if I should pay for someone else's shoddy work! But I'm stuck. I can't just dump this car as I'm still paying on it. I can't just run out and buy another one because I think I mentioned the single mom of 5 on a budget thing....
I'll end up having to pay for it. But heed my warning - DO NOT EVER BUY A CAR OR TAKE YOUR CAR HERE FOR REPAIRS! YOU WILL REGRET THIS WITH EVERY FIBER OF YOUR BEING!
