Poor communication and diagnostics

I dropped my car off at Hyundai Bedfordview 3 weeks ago. There were a few issues with it, and I expected they would call and let me know about the problems and also expected there would be a cost and that it would take some time to fix.

Day 1 went ok, with them calling to explain the issues and the fact that they would have to order parts from overseas which would take 10-14 working days, before they arrived and then they would do the work. Yesterday, I called to get an update, it has now been 16 days without a call from them. They then told me they had fixed one problem, but had now found another two which were going to again need parts from overseas and would take another 10-14 days. Surely as a service center you run a full diagnostic the first time round and order all necessary parts. The frustrating thing is that I had to call to find this all out.

So here I sit, having to pay for a rental car for another three weeks while they wait for parts. And given there track record, who's to say they won't tell me the same thing in three weeks' time?

Massively disappointed with a car company and service centers I have always enjoyed up until this point. Makes you think about using private companies and mechanics going forward.
