Lack of customer service

Emailed momentum regarding a dental procedure asking them for their advise on which practice they recommend for this procedure.

Their dental team responded to me with a no-reply email telling me I need to get a quotation and an x-ray.

But they did not advise me on any practice in the network and I cannot respond to enquire about this. I have been a customer for a year who also pays on tine every month.

When I call them i am stuck on the line and no-one answers the phone.

How is it so difficult to provide customer service to a paying customer whose initial health should be of importance? Is it just a case of pay you to feed us admin?
