BAD, Horrific service

what a headache dealing with Momentum, 2 weeks ago I kept on sending emails to samuel T****avhani which he never answer them until I asked Brent Kur to assist me only then Samuel come back to me and assured me the email was send to the dealer to fix my car, Only this morning when I Call Autobody they didn't receive my car and they can't help me without the authorization send to them, Then I called momentum then the lady by the name of Lerato Motsoko answered the call and I explain to her what is happening which it was not sweet at all as the whole conversation was threatening me that she will hung up the call, I am so tired with momentum service which they never take their client serious ever and this is so BAD as i am paying for that service
