The most pathetic communication & service

My Hyundai i20 was towed in to Hyundai Weltevreden last week Tuesday and it took them the whole week to let me know what the problem was on the car after numerous phone calls to them. Then Friday when I contacted them they gave me a ridiculous quotation of R12200 to repair the clutch whereby if they supply me with their clutch kit only its R3269 which means their labour work is R8931!!! Ridiculously insane!!! This morning I phoned Hyundai to let them know that I will not be accepting their quote and my husband will be picking up the vehicle today and when he got there they told him that they wont release the vehicle until the towing fee of R1150 is paid and this was not communicated to me beforehand that I would have to pay first before I can fetch the vehicle! Already we had to pay someone to come tow the car from Hyundai to another service centre that gave us a reasonable quote which means its money wasted and petrol wasted!!! And yet when the car was towed to their premises their boom gate hit my car and just to find out who will be responsible for that was a huge back and forth to the towing company and hyundai weltevreden until I had to speak to the service manager at Hyundai Weltevreden that confirmed that they will cover it, however the vehicle has been sitting at their premises and yet not making any plans to fix that dent while the car is there.

What does Hyundai assist cover exactly??? because I find it useless and I feel like it should not be part of my installment, it should be canceled and my damn installment should be less!!!
