Email to the seller concerning our missing contacts

Me and Alyce ordered 2 more pairs of contacts for our music video as I mentioned in my previous post. I emailed the seller asking them why they haven't been delivered, and they replied and said we will get a full refund, therefore we need to order from another seller. We are going to order them as soon as possible so we can carry on filming. However, me and Alyce had a discussion and we think it'll be best to only order 1 more pair as we feel we have enough footage of her. We need more insert shots of random things e.g the sky, candles, the burning picture etc.
