Disgusting service from Innovative Group

I recently bought a car in Feb and was told that I have a 2 year warranty for any mechanical problems with Innovation Group. My car has started giving me problems with the gearbox and I tried calling this Innovation Group but haven’t been successful in getting through. I hold the line for more than 10 mins with no answer. I got through to the switchboard and spoke to Zanele who asked if she could direct my call. As I was trying to explain to her that I’ve been trying to get through with no luck, she cut my call and transferred me anyways, back to the same people who are not answering. I found that to be extremely RUDE and UNPROFESSIONAL!!! I am not happy at all!!! So now, I’m paying my premiums every month but when it comes to delivery, it’s appaling!!! Can someone please attend to this matter because the service I’ve received from this company is the worst!!! I wouldn’t recommend it to anyone!!!
