Terrible Service

After booking in my vehicle for a service on the 16 April 2015, it was discovered that my vehicle required additional work. I advised the concierge that i have a motor rite warranty and they require a technical report from the workshop. Its been 2 months later with numerous calls and email even spoke to the \Branch manager"which i followed up on but still till now i have received no response and just been give the run around that they will get back to me. I find it appalling that after speaking to a branch manager that you have to call for updates. """
