At this point, for your iPad Pro, it is really too late.
Apple will not help you get a free or cheaper replacement since you never purchased the extended warranty.
Your options are now limited to purchasing another replacement iPad Pro of your same model, at a 40% discount, purchase a new iPad Pro for more cash, or purchase a discounted, refurbished iPad Pro model from Apple's Refurbished & Clearance section of the Apple Website.
If you purchase a new or refurbished iPad, you have up to 60 days to purchase the extended, two-year AppleCare+ plan.
If this is truly an actual Apple authorised product reseller/repair center, you can certainly let them know about your concerns via this link.

Since you had a 10.5 inch iPad Pro, if you want to purchase something similar that will be cheaper, you could look at the new 2019, 10.5 inch screen iPad Air 3 which uses the same 1st generation Apple Pencil and shares some of the same specs as the 2017, 10.5 inch screen iPad Pro for less cash.
iPad Air - Apple
The new 2019 iPad Air has some better internal specs than the two-year old, 2017 iPad Pro, like a faster CPU, slightly less internal RAM ( 3 GBs of RAM, instead of 4 GBs ), better spec'd front facing FaceTime camera ( but poorer spec rear facing camera ), only a two speaker audio system ( instead of the 4-speaker audio system found in the Pro iPad models ) and NO 120 Hz screen refresh rate.
And lesser storage size options for the 2019 iPad Air models.
Still much cheaper than the current iPad Pro models and maybe still cheaper than refurbished, two-year old, 10.5 inch screen iPad Pro models.
Best of Luck to You!
