Why is the local store phone number located in Sri Lanka? Is it hard to have people in store answer the phone?

All calls to stores are routed to an external call center. Stores are unable to receive direct calls at this time due to staffing shortages.

Call centers have taken over those functions for a lot of companies

When I Google the Henrietta store it's a 585 area code

As an employee I can confirm all calls to local stores are routed to an external call center. If you have questions about a curbside, in store pickup, or online order, call and have an order number ready for the agent to assist you.

Not sure why you think the local store phone number is in Sri Lanka. I've had the number stored on my phone for years and it's country/area code +1 585. In the last 18-24 months, yes they are not staffing at 100%, but the phone system has been working through an automated system for, again, years... This is true of vast majority of businesses apart from very small local establishments, in my experience.
