Tyremart not good

I had to replace the shocks on my F30 BMW and opted to go to Tyremart in Rustenburg. I replaced the rear ones first as they were worse than the front ones and a week later, I replaced the front shocks. After the fitment of the front shocks, I could no longer drive faster than 100km/h as the car would then vibrate as of it's about to fall apart.

I took the car back to them and then send me for a shocks test which indicated that all four shocks were wrong, but Tyremart said they'll only replace the front ones since they were the ones, I complained about.

After they fitted the new front shocks, the car still vibrates and it's sitting higher at the front than normal, and I can't even drive at night as oncoming vehicles believe I'm driving with my brights on. The right front part of my vehicle is even sitting a few millimeters lower than my left side.

I regret ever making use of their service.
