Disgusting co to work with

Went into Midas PTA north,game the make model and year of the car, the gent looked it up on the system, gave me a belt , I paid and left on trying to fit the belt it's far to big . Now I must drive all the way back to exchange it . Disgusting service. I had engine no and the vin no he asked for neither. So instead of saving money it's now costing me more to go back , be careful of them they thumb suck the part
