Useless Callcenter Support (even after 4 agents still no assistence)

Spoke to a discovery agent on 26th October regarding the purchase of an Orthopedic chair using my MSA. She instructed me to use *** to direct my query to, which I did...I called for follow-up yesterday and was told it's the wrong email address, then told to use ***, only to hear this morning it is also the wrong email address, before the agent could give me the new email address the call cut, and he didn't call me back, I called again and spoke to another agent who was trying to find this email address and her call also now dropped; I am so ****ed to talk to a call center person....I want to talk to a manager or someone who knows what he/she is doing...
