Disgusting service

Good Morning I visited Supaquick (Armadale) to check on my exhaust and possible replacement of the flench gasket for my car (Nissan Livina) which i tried to get and could not find even from Nissan. My exhaust was checked, the guy suggested a replacement for the gasket and closing some of the leaks. A lady from reception was called to assess. She gave me a quote for the leak and suggested that the gasket be removed to have a sample. I explained to her that i tried everywhere else but could not find the gasket, where would they get it from. She said, "we have our contacts". I checked with her if she is sure she will get it, she reassured me. I even asked if it's not possible to call first before removing the gasket, she said they will definitely find it. This was not my first time going there to check for the gasket, in November the same lady phoned around and could not find it, said they will continue to look for it and I can come back anytime. this time around no phoning but removing the gasket. I asked how long will it take to get it, she confirmed 30 minutes. In 15 minutes time i was told they did not find one. I asked the guy who they said went out to get it, he said he went to Beras motor spares to check it. Beras motor spares is in Alberton he would not have been back in 15 minutes nor 30 minutes, maybe an hour and a half if lucky from where we were. (Armadale to Alberton North) I was then charged for refitting which i think it's unreasonable cause they removed the part knowing they would not find it and they and to make money out of the refit. Beras has an open line for checking on the availability of parts. I had mentioned to the lady that i checked Beras ,Nissan ,Kotwals and many others. I would understand if they had called, and the spares had doubts and asked for the sample. but nothing of that sort was done. The first time the correct procedure was followed and i paid for checking. second time i was prepared to pay for the checking and fiting of the new one but i ad to pay for the refitting of the same old leaking gasket. This is extremely poor service not impressed at all. When i went to the reception lady to complain, there were 2 ladies a colored and a black lady, they just ignored me and left me there talking to myself. Extremely dissappointed
