Bill increased on a price locked contract

Hello @user_91d15e Thank you for reaching out to us on our forums. I hope that you are well today, and please know you are in the right place for help. I have been assisting many customers recently due to us receiving the first statement since our prices for equipment, fees, and services recently changed. With a promotional rate that is on a timeframe the cost of the service should not have changed, but you may have seen a cost change if you rent equipment and if you have a service that saw a change in fees. If you look at page 3 of the statement you will see a breakdown in the charges and the first item should be the rate for your services. Below those details it will show you when that promotional rate will end.  

I would be happy to go over the details with you in a direct message if you have any additional questions. We are here to help 24/7. I just need your name and service address sent by direct message.
