Priceline complaint: Priceline coupon

I book d a hotel feb 20 2023 for Baltimore airport comfort inn for husband Andrew White. The hotel was absolutely horrible. Tv was not working no clean linen would not transfer to another room. I contacted Priceline for help the reached out to hotel no response. I was told for my inconvenience they would email me a coupon for a discount of 20% to use on future reservations. I never received a coupon so I called Priceline on May 7 2023 explain to the representative what happened and they transferred me to a supervisor to talk to them about the coupon discount that I never received. I was told a coupon was sent to me and I explained to them I never received it I verified my email address I was told they will send me another coupon did not received again. I called and spoke to a supervisor by the name of joy in the Philippines and another supervisor by the name of Ron who was also located in the Philippines and I was told three coupons were emailed to me. I explain to Ron who was the last supervisor I spoke to you that I am not receiving the coupon is there anyway they could apply the 20% to the reservations I had already booked for Oklahoma arriving on May 8 Ron told me he could not apply the coupon. The conversation with Ron went nowhere he was not trying to help me I think that it is ridiculous that a coupon cannot be added to the reservations I already paid I asked if he could mail me the coupon in the mail he told me no. If you take a look at my account and you will see that I am a VIP member that I book hotels car rentals and airfare using Priceline and because of that we became a VIP member and certainly I am not being treated as a VIP member. I truly wish someone can call me back because the service and I am receiving is absolutely ridiculous and horrible no one is trying to help me or to solve my issue. I can be reached at 770-907-4671 my name is Anita White and my email address is [email protected]. I hope you will respond and correct my issue, thank you.,
