Who will be handling my account and do I have a dedicated account manager?
You will need to know if there is a dedicated person who will be assigned to your account. This is a designated individual who you can call and has authority to act on your requests. If a call center is assigned to your account, then be prepared to wait longer for a response to your request.
Furthermore, ask the company who your dedicated account manager will be and ask to speak to them directly in advance of making your decision.
