Worst car repair ever

Dishonest - in January I installed a new battery with a 12 month guarantee. About 2 weeks ago I start to struggle to start the car. Had the new battery and alternator tested. Not the problem, but something was draining the battery. So I called womenmechanics to assist. I explained the problem and that the battery is currently flat. He came to collect car.....without a charger or jumper cables....car was with them for 3 days ans still they could not tell me what is wrong. Eventually when I requested that they return the car I was told the battery was wrong make for my car. ........ so got the car back, take it to battery shop again to double check only to find there is now a old dirty different battery in my car!! Reported it immediatly to womenmechanics andgot a we will resove it back. Still waiting. Please do not use them.
