You must know how marketing campaigns work!
The larger the company is, the harder it is for them to implement new things. Especially something as unique as Go800!
Imagine Chase start telling its customers to use Go800. First off, they must be 100% sure Go800 will work. so they would be testing it out for couple months. second, when they decide to use it they have to implement it in their next marketing campaign, which could be few months away. there are also lot of costs involved in that...they have be broad within the whole company too...perhaps every single branch..printing out brochures..letter heads, etc and tweaking lot of forms...
But Ike said lot of companies are working to use Go800 within theirs ads already... so it is just the matter of time.
