POOR SERVICE AND COMMUNICATION

I handed my car (Hyundai I30) in for service on 02/02/2015 due to a ticking noise I heard in the engine. It's been more than a week now and I have made numerous calls to Hyundai to try and find out what's happening with my car and they told me that the head has gone to the engineers and have not come back yet. Hyundai has refused to give me a loan vehicle to use in the mean time and this has gone on for far too long. I keep calling for an update and keep getting the same unsatisfactory answer: \The engine head has not come back from the engineers yet."No time frame as to how much longer either.<br> <br> We have purchased 4 Hyundai vehicles over the past 4 years and I regretfully have to admit that the after-sales service is pathetic. Shall I expect my business to stop running too if I should have a problem with my H100? Some prompt assistance regarding this matter would be greatly appreciated.<br> <br> Many thanks"
