Day light *******

My mini cooper had an engine problem of which when I fist brought it in it was supposed to be 13000 because oil was mixing with water I struggled to get a quotation when they heard I bought the car from we buy cars and that they will be paying suddenly the quotation is now 100008 not the amount that I was promised when the car was fist brought in when I refused to pay that amount it now 14000 just for labor no parts when I refuse that also I had to 4500 just to get my car back in pieces .maybe with parts missing I have never experienced such unprofessional rude and ****** in my life of which I would never recommend them to anyone even if they were the last garage on earth .
