I am an assure customer, i want to speak with a tech rep by phone
I don't know whether or not Assure customers used to have a different number to call, but all I can find at present is the Contact us link https://support.microsoft.com/en-us/home/expcontact?
You're sure that your Assure plan is paid/current?
**Note:**Effective March 2021, our assisted support subscription, Assure, is being retired. Existing Assure subscriptions are still valid, but you won’t be able to renew at the end of your subscription period. Subscriptions with recurring billing turned on will be allowed to expire.
At https://support.microsoft.com/en-us/home/expcontact? you will be sent to the Virtual agent. Work with the VA for a few steps then tell the VA, perhaps several times, that you want to speak to an agent.
