On 14 January 026 I visited them to do a Pension promo ,which included tyre rotation, balancing and wheel alignment. All my cars wheels have lock nuts . I Left the premises and continued with my daily c****s. A few weeks later, on Monday 02 March 026 when washing my vehicle I noticed that the lock nut and plastic nut cover were missing on the front wheel. I immediately proceeded to Supa Quick and informed the manager about the missing parts. He failed to acknowledge that the serviceman who had worked on my car was at fault , by not replacing the lock nut and cover. He said anybody could have removed it. My car was never serviced or been attended to during this period. Instead, he offered to sell me a set of lock nuts for R550, which I thought was a slap on my face.Why should I now fork out that amount of money, knowing that they were negligent without checking that the job was completed correctly.
