Fasttrack Immediate Care

I took my daughter to FastTrack in 2018. I did not receive a bill until a year and a half later. I made a payment on the bill, 2 months later got the next bill, made another payment, and then didn't receive any other bills for the next 3-4 months but received a letter from a collection agency. After posting on social media, I found at least 20 other people that this has happened to. This is ridiculous and unacceptable. I will never step foot in there or recommend this business to anyone.
