Disgusted by behavior

I am an essential worker during this trying time and my vehicle has been towed by Renault on Monday morning as it needs repairs on a part that was replaced a few months ago but is now defective. I have been trying to follow up to find out on the progress on the vehicle and the lady that answered today was totally and utterly rude and disrespectful, she actually hung up while I was talking to her. The frustrating part is that I myself have to report to work tomorrow morning but have no idea how that will be possible if I don't have my vehicle back. It has been 3 days and I have not received any feedback at all, I am the one who constantly has to keep calling them. There is absolutely no need at all to undermine each other especially because of race and be rude...
