Daycare wont cancel payment

My daughter is attending a daycare that’s like 30mins drive away from us (so 2hours drive each day). I know it’s far away but we urgently needed one, and they were the cheapest we could find since our finances aren’t doing well we even explained them our situation and they gave us a special price, and they love my daughter so much! But Now with these crazy gas prices it’s getting more expensive and my husband has now two jobs so it’s complicated to drive her there in the morning, we found a new one in our area. I already paid for june last week but I told them Wednesday that we have found a new daycare and that my daughter’s last day will be tomorrow. I wrote the boss to let him know so that he will cancel the payment but he doesn’t answer. I called him but he doesn’t pick up. It’s been three days now and I know he has seen my messages. Now I don’t really want to go to the daycare and go wild since they have been so nice since the beginning but I’m starting to loose patience. Its obvious that he is ignoring me
