Business ProfileforGO Airport Shuttle

I ordered a private prime time shuttle to pickup on May 27, 2022 at my home and drop-off at *** airport at 5pm. At 4:10 the driver has not shown up so we contacted him and he told us he could not pick us. We then got a call from another driver who said he would be there in 5 mins, however after 15 mins he was a no show, so we contacted him and he said he wasn't able to take us. At no time did Prime time shuttle contact us to notify us that our reservation was not going to be fulfilled or to provide an alternative. We called Prime Time Shuttle but where put on a lengthy hold. While on hold with Prime Time Shuttle we looked into getting an **** but the next suitable (for #passengers/#luggage) available **** was 18 minutes away, so we made the decision to drive ourselves to the airport as we had an international flight to catch and should have left our home 40 minutes earlier. We had to arrange long term parking on the way to airport at a cost of $446. We contacted Prime Time on the way to the airport and requested they cancel/refund us for our reservation. Upon return from our trip I have emailed them twice to ask how I can submit a claim to be reimbursed for the parking but they have not responded.
