Welcome back! 🙂
This rarely happens, but we have seen it before, and in almost all circumstances PRICELINE will rectify the situation, it will just take some legwork to get to the right person/department that is authorized to make the correction.
What hotel did you receive, what is the address that PRICELINE provides, and what are your dates of travel? (just to understand how quickly this needs to get resolved, as if your stay is in 2-3 days the urgency is quite different vs if your stay is in 2-3 months)
