Reconditioned CV Joints

On the 12th of December 2014, I fitted 2 inner and one outer CV joint at Villeria CV joint warehouse. Few days later when I was driving, my car started vibrating. I took the car back, the mechanics st********** the CV's and worked on them, then placed it back. I drove the car and the same thing happened. I then took the car for wheel balancing, alignment, the same thing carried on. When I took the car to the Toyota dealership, they confirmed that my car had re-conditioned CV joints that is the reason for a vibration. I took the car back to Villeria CV joints repairer last week, they basically treated me like an animal. They told me that they are not McDonalds, where I can buy stuff and just return it as I please. I feel as a customer, they should have considered my report from Toyota, and replaced their old cv joints that they sold me. What upsets me the most is that we see a lot of fatalities in our country, and what causes these accidents at times are the defective parts that we buy from the so called \reputable places". I must admit"
