Useless techinicians at Hi Q Phoenix

I normally have good service at Hi q however when I went to the branch in Phoenix KZN I have lost all hope I changed my rims in Phoenix and did a swop over from my old wheels to the new set. Requested balancing of all wheels and did have good service at reception and the manager over seeing however upon driving back to Johannesburg discovered my wheels had a big shudder over 100km per hour Surely the technicians balancing the rims would have picked this up. I had to go to supa quic back in centurion where I had to pay an extra R350 for further checks and re balancing where they easily picked up the issue and advised why the balancing could not be done. Now I know I will have to repair and they will assist. Why did hi q not pic this up. I have no idea. I ended up driving very uncomfortably back to Johannesburg and then inconvenienced to go to another tyre place and pay extra money for a check. Hiq has lost a customer. Wish the seniors of hi q address this with the Phoenix branch and they will lose more and more clients
