New plan not setup

Hi we had a service person come to upgrade our current internet setup. They weren't able to upgrade us to 3gb but said we could do 1gb. They said it would be $130 but I had negotiated over the phone $97 for 1gb or $112 for 3gb. I told them I wanted 1gb for the price I was quoted on the phone, they said they would get back to us but I haven't heard anything. How do I know if this is being done???
