Empty promises

Totally disgusted with the service received from Randburg Motorcycles. They sold my husband a bike with gearbox problems, according to the sales person, he said that he has sent it to his technical department whereby they have said that there is nothing major wrong with the bike. My husband didn't even drive the bike for more than a month and the gearbox packed up whereby the total cost for fixing this is R 15 000.00. My husband sent a qoute (the qoute was for ONLY opening the gearbox and see what the problem is inside and came to a R 7000, just to find that the gearbox is broken) where they said they will pay half of the damage. Now that we paid the R 15 000 and requested payment now suddenly Mr Powell is not working there anymore an nobody knows of the empty promise. Even though it was sent via email and in the email was mentioned that it was decided that Randburg Motorcycles will pay 50%.....
