Hi bizzy,
I'm sorry to hear that you received conflicting information from our support team, but the fact of the matter is that the Multi Account Plan is only offered in some cases as a courtesy and each request is evaluated on a case by case basis.
There are a variety of factors involved in determining whether a request to be placed on the Multi Account Plan can be approved and, in the event that we decide to decline a request to utilize this plan, we will not necessarily be able to provide you with a specific reason your request was declined.
