I got regular calls from my cellphone provider about offers until one day I had enough and told them if they call me once more I will cancel my contract with them and go out of my way not to do any business with them again. If they want to show me an offer they can just send me an email. They didn't.
Generally my advice is to never agree to anything via phone. Tell them to send you the details. They always try to use the heat of the moment to make you do things that might not be in your interest. If it is really a good offer it will still be good hours later when you read the actual details.
