Hertz in Memphis, Tennessee

I reserved a minivan back in March of this year (2017) for today July 27th at the Hertz location on Covington Pike in Memphis, Tn. I get to this location about 30 minutes before the time I actually supposed to pick up the mini van and the guy at the desk tells me they do not have what I reserved months ago. I am livid at this point because I called the day before to see if I can rent the van for Wednesday instead of, Thursday for the same amount of time which was a week rental. The guy at the front desk tells me he can call around to the other Hertz to see if they may have one, so I become more livid because it's not a guarantee that I can get what I reserved, so not fair. He did offer me a 7 passenger vehicle but that wouldn't do because we have a Dodge Journey at the house and the third row do not have any leg room. He offered another 7 passenger vehicle but that still wouldn't work because I want my kids to be comfortable traveling on a 24 hour ride, I asked him would that vehicle be cheaper he said No and he can offer me a free gas. I am still livid at this point because I am still here and it after the time I initially had the reservation (30 minutes after). Hertz is the only company I typically rent from and this particular incident has gotten me to the point I WILL NEVER RENT FROM HERTZ again..... Still after 2 hours I am still waiting, they told me that they went to get the van from a different location and came back to the Covington Pike location, they told me that I still had to wait so they can get an oil change on the van... At this point I should have went somewhere else bit I wouldn't have gotten the same rate... I'm livid

Obtaining the vehicle was fine. The waiting to return the vehicle was not . 4 customers waiting. Three employees visible upon my arrival. One left. One said, I'll be with you in a minute. She left. The one employee was in the back break room. After waiting for over 20 mins., a customer went to the back and told him that no one was working the front desk. 10 mins. Later he walks to the front. He was helpful. Customer service is gone.
