Business ProfileforM & M Limousine

I booked a 14 passenger sprinter limo for 2 one-way trips to be done on 12/24/23 to take family to a play in ******* and then a ride home from a restaurant to the same home in the suburbs.When I called to book, I was quoted for a 14-passenger van and a higher rate ($223) for the limo. I decided to spring for the limo.On 12/24/23 a passenger van arrived at my home. I immediately called M&M limousine to report the wrong car and was told their limo was out of service. We still needed a ride so we took the van and I was told I would be given a 15% refund and I would receive a call from management after the holiday. The same style van was used for our trip home.On 12/28/23 I still had not heard from the company so I called and the person I spoke to said they knew that I had been given the van for the rides but reported no ticket was filed. They did agree to refund the 15% each way.Today, 1/12/24- still no refund in my account. I called and spoke with ****** who said no refund has been processed. I asked to speak to management and he said that was not possible but that he would let them know.Total $446 paid for 2 limo rides The service provided was 2 passenger van rides. I was told twice I would get a 15% refund per trip. As of today no refund has been issued.I do not know what to do at this point. Please advise.Thank you.***************************
