ltc exhaust

I booked my car in with this garage after finding their details on black circle. I was abroad at the time of book with just a day back in the UK. I shouldn't have told them this as they used this to their advantage and told me the tyre would be an extra £30 to what I was told on the phone. I was at the garage and had no other choice. I like to keep my money I the local community and shop independently where I can but sadly they've ripped me off. Won't be returning for the other 3 tyres next month!!!!!
