VW damn bad service

Today, I have never experienced such extreme bad service ever in my life from Volkswagen. I bought my car last October 2020 with 118 000 Kms from Webuycars, MFC financed my service plan and 24 months warranty. I was adviced by the service advisor to bring my car when due for service at 135000kms and when I brought the car. They didn't change the cambelt and told me everything is fine, the cambelt will changed in the next service interval. I took the car at 150000kms for service, I was told everything is fine and when I asked about the cambelt being changed and they told me it is still ok. I drove the car for 1day, warning light appeared and took it back. They informed me filter plug was not plugged properly and it has been resolved. I drove it for 2 days same warning light appeared, I was told the vehicle is out of engine timing due to cambelt on being changed. I am still shocked that why I was not being told during the service that I need to replace the cambelt and innovation group told it was covered in the service plan. I engaged the Acting Manager who referred me to the service manager "they asked me who problem is it". I mean when you arrived at these so called dealers they display FAKE certificates and you think they care for their customers until you have extreme bad service experience. As for innovation group, you pay for warranty that says they cover mechanical parts listed in their schedule and when you claim they want proof of the replacement previously. This situation reminded me of polo engine being damaged after taking my car to VW Hatfield and after several engagements, they told me everything is fine. Surprisingly, my car engine got damaged. I had to sell my car for less price and buy the one I am driving now and I am experiencing the same bad service. VW brand is a fake brand, all they want is your damn money to dry you broke and they don't give a damn about your needs. I won't recommend my family, friends, colleagues and anyone to use them just like MTN. You think you going save money through petrol usage through buying their car. to hell with their discusting brand! I will never buy the cars after this one, I rather walk and use Uber. They can keep their sticky cars!
