Business ProfileforCookie Monstah

I hired the Cookie Monstah food truck to serve ice cream sandwiches at my wedding on 6/18/2022 from ****pm as a treat for our guests. We had paid $1,527.08 for 155 ice cream sandwiches to be served. Sometime after 10pm there was an issue with the trucks generator and the ice cream started to melt, resulting in them leaving early (before 10:30pm) and us not receiving the 155 ice cream sandwiches. The truck employees spoke with my husband directly and told him that they were going to pack up and leave. They told him who to contact for a partial refund. I have reached out via email to see if we could get the partial refund and since then they have completely denied that the truck had any malfunction at all. I have many witnesses who were turned away when they went to order a sandwich and ones that spoke directly to the employees on the truck that have confirmed that there was an issue and the truck was not working. I have never dealt with a company that so strongly denies what actually happened. An up front apology would have been fine but the fact that they keep denying what actually happened is just insulting. I would like a refund from this business for not fulfilling the job I hired them for and continually denying that there was any truck issue from the start.
