Terrible service & no regard for customer safety

Extremely disappointing level of service received from Mercedes Benz Sandown, Sandton. A quick summary is below for your convenience:

1. I took my vehicle in during October 2020 for a service and was informed that there’s a factory fault with my seatbelt and that the part would be ordered. Vernon committed to calling me once it arrived and arranging for installation. This did not happen.

2. My partner and I have been driving the car more frequently in 2021 and have been doing many long distance trips. I recalled the fault and got in touch with Vernon about a month ago. This was after much pain dealing with the individuals in the email trail (getting someone to respond did not prove trivial - please read through the trail). It turns out the part was ordered and was available but Vernon nor anyone else bothered contacting me.

3. I took my vehicle in and had the seatbelt installed. Upon pick up I was told by Vernon that the seatbelt that was ordered had a fault and the belts were frayed. This was very inconvenient but all that could be done was to wait for a new part to be ordered. Upon conveying my frustration, Vernon promised to have someone pick up my car and drop off once the part arrived.

4. The pick up, installation and drop off happened as expected about two weeks ago (or so I thought). This evening, for the first time, the passenger seat was occupied and we realized that the seatbelt was not installed properly as it does not clip into the slot at all.

At this point, I no longer know what to do, as it’s extremely annoying to continue in this way. Further I have very legitimate fears around whether the seatbelts would even operate as expected and whether the airbags would release upon a collision. How am I to have any faith in the level of service provided?
