VSP Customer Service Issues

I will be changing my insurance provider effective January 1, [redacted]. Currently, I have VSP coverage through Medical Mutual. As of next year, I will have Blue Cross Blue Shield as my insurance provider, which will also cover my vision care through VSP. I am wondering if my VSP account will be automatically transferred from Medical Mutual to BCBS or if I need to cancel my current VSP coverage to avoid being charged twice. If cancellation is necessary, could you please provide guidance on how to proceed with canceling my current VSP account without any issues?

I recently had an eye exam where I received a prescription for two pairs of glasses. I inquired about having them made into trifocals instead of two separate pairs, and they confirmed it could be done. When I tried to pick up my glasses from an in-network provider, they mentioned a co-pay of $90, even though my insurance indicates that with BSP, the co-pay for lenses should be $20. They explained the difference was due to them being progressive lenses. Could you please confirm if this information is accurate, or if I overpaid for the lenses?

I attempted to reach customer service but the automated system required my phone number before connecting me to a representative. Despite entering it three times, the system did not recognize it, resulting in disconnection. I need to confirm if my children, S.B.H. (8 years old) and J.H.H. IV (5 years old), are included in my VSP policy. If not, I would like to know the premiums for adding them. I was directed to contact VSP through the provided customer service line for this inquiry. Unfortunately, I have been unable to speak with a customer support representative through the automated system. I can be contacted at [redacted] or via my work email at [redacted] As it is currently the open season, I wish to make this adjustment within the specified timeframe.
