Trouble Postponing

Hi ladies. I was wondering if you all had any advice for postponing. My wedding is in May, but my venue is being super hesitant with me. I had to call them daily for a week just to find out if they would be allowing weddings to be postponed, then another week for them to verbally confirm that they moved my date. They said that they would send me over the new contract on Monday, but it is Thursday and I still don’t have it. I’m so stressed, I don’t feel secure enough to change my other vendors until I have the new contract. It’s keeping me up at night. Anyone have any suggestions?
