Even though I have consent authority on my clients accounts, they still don't want to talk to me and say the signed consent doesn't allow me to speak on the clients behalf. Then why have several Synergy people told me to submit consent forms so that I can speak on my clients behalf - its a legally binding document signed by the account holder giving me permission.
Make your minds up Synergy, your customer service is shockingly cr@p!!
