Billing Issue

I recently received a bill for $1260.00. I simply do not have that money to pay, you are more than wiping me out. On top of that, I no longer need a three-user account, as it is just me. Can you please downgrade my account to just me (single user) and can you help me get a refund for the excess. We are just a tiny entity. We’ve had some major setbacks as of late, but we’re trying to turn things around. This will wipe us out right now. Please help us. Thank you, Kyle
