Issue not being solved

Hi guys so this is what happened, so on the 9th of June I sent my car to Hyundai due to alternator issues since I'm still under warranty, they gave me a feedback on the 14th of June which was that they found alternator rotor and rectifier requires replacement.

They gave me a time frame of 14 to 21 days as they awaiting for the above mentioned parts to be shipped from Korea to South Africa. I then received a call from their service department advisor stating the exact date which the parts will arrive here which she said on the 19th of July.

I tried requesting a courtesy car in the meantime since I use my car to earn, my car is my job no car no money, they told me that they don't provide courtesy car no more to clients. On the 14th of July I then received another email stating that the parts will now arrive on the 8th of August, sadly.

I’m unhappy with the service and I need the issue resolved urgently cause my livelihood is suffering cause of no income. Hope this resolved urgently.
