Poor management

I'm rating them 1 star as there as the 0 star option is not available, i sent in a car (mini cooper) to have gearbox repaired/replace, with this the agreement with car clinic was "if do not follow through with they replacement/repair we would not reinstall it and leave gear box in the boot" which i agreed, later i then contacted Eugene (Reginal manager) regarding the pick upon my arrival i would find that they have installed new gear box without my consent and i ended up paying for a tow truck to waste his time and my money ,i then brought it up with Eugene and he made it very clear he was not aware of the installation as he has many stores to manage which does apparently not include my car ,i then brought forward my frustration after i paid for the "Strip & Assess" invoice to his attention, Ackording to Eugene "this is not my problem as i did not give the go ahead for this work to be done" i kindly ask if he would then reimburse me as he broke the original agreement and i now need to pay for another tow truck and he made it very clear this is not to concern him

inclosing i always serviced both my cars at this branch and felt i could trust them however if this is the person who is the last resort in resolving issues i would not come back there and would not recommend anybody to go there either, again this is not a reflection of the branch just Eugene who handled this matter poorly and with no empathy from a clients perspective
