Discovery WTV624GP - rims and tyres replacement takes over a month.

It has so far been over a month to replace three tyres and rims, do alignment and balancing. A job which can be done in a few hours, actually it can be done in less than an hour at any tyre shop. Renew-it Rivonia communication is disgracefully poor. The allocated service agent is always too busy to answer calls and never returns them. The service manager doesn't communicate with the service agent who is not allowed into the workshop or given updates on the vehicle progress. There is no transparency into wherein the process one is or what is causing delays. Emails are returned after long delays and I'm only given back just the same online status: panel beating / mechanical. What a horrible customer experience so far! I am still awaiting the vehicle...
