POOR SERVICE

Good day<br> <br> I booked a car and collected at the Sandton sun branch on the 11th of Dec 2015 and returned it to the Sandton eye branch on the 14th of Dec 2015. Two weeks later (29 Dec) after returning the car i phoned the Sandton branch to find out when i would be receiving the invoice as i had not received it as it normally does not take this long, i was than informed that they cannot process my claim because there was damage to the wiper, i than informed the consultant that the wiper was faulty already when i took the car but did not notice as the guy who was inspecting the car before i took it did not check it, i only realised later that day when it started raining that it was faulty and i filled in a query form when i returned the car. I have been calling and nobody seems to know when i will be invoiced and i was informed that the car has been sold so they are also not sure if it was sold with the damaged wiper which will mean i am going to be charged for a wiper that was never even fixed since the car is no longer there. And another thing i fail to understand is if the consultants cannot assist me who is supposed to assist? Can someone who at least knows whats happening assist me.
