It's been six months, i want my wedding video.

Ok, so last year I made the decision to hire a videographer for our wedding, I paid the full amount of $1,000. I had asked the question when booking when could I expect my video (now I know it was on the lower end of typical videographer, and I am aware that you get what you pay for in most cases. ) and in an email the videographer had mentioned since my wedding was in October there is back log of 3-5 months. I was ok with this because it was the only way I could afford videography. The videographer was supposed to put together a highlight together for me so I could see something. He didn't. I followed up on January 9th, and got a somewhat annoyed response that he was mad I was asking for it after 3 months. So I have no highlight video, and I have no video, and I was promised I would get it in 5 months. Our wedding was October 13, for reference, but I was waiting until March 13, for it to be a solid 6 months. Should I wait until March 13th to follow up or should I be more firm in an email, and mention that I want my video or I will dispute the charge on my credit card? Now, I know it wasn't the most expensive package but it was still expensive. What should I do? How should I approach this?
