Before a single call is made everything must be agreed by both parties, from qualification process to what is being said, communication throughout the campaign is paramount, if things are not going to plan you have to choices,

b) work with them to find out what is going wrong, is it a bad time of year, is it that people do not really understand the product//service. There is always an answer for any campaign going wrong, you just need to find the right angle
