Brought my grandchildren here on a very hot sunny ...

Brought my grandchildren here on a very hot sunny day, and rented a stroller which was in very poor condition and repair, the sun shade was broken and there was mold and mildew all over the cloth part of the stroller. didn't realize the sun shade didn't work until a few hours later when I actually needed to use it. Left the zoo early because it was too hot for the grandchildren and spoke to the manager there who was unwilling to return my $8 rental fee and offered little to no concern for the situation even though I told her we had to cut the day short. She offered to give us a different stroller, but by this time the children were so hot and aggravated and so was I, so we declined. you would think that before they actually issue a stroller to a paying customer, that they would check to make sure it was in proper working order and clean. Unfortunately this was not the case . I will not go back due to poor customer service, not to mention there weren't many animals outside of their enclosures within the fence, I'm sure due to the scorching heat of the day.... not a fun day at all.
