Poor customer service

I had a bad experience, I paid for my trip 5 months in advance and I was only told 4 days before the actual trip date that they are cancelling my trip because I was the only person that had paid for that package and therefore they will have to refund me or alternatively I must pay extra money to upgrade to be able to go on another trip, so because I had invested so much in that trip and I was really excited about it because it was my birthday week, I had to pay the extra amount even though I wasn’t happy. The communication from the owner and her team is horrible because if they had told me at least 2 months earlier that they might have to cancel the trip , I could’ve made other plans. I really wish they had treated the matter differently because they were the ones at fault, I was poorly treated as a returning client
