First of all, if you call the phone number provided with WalkInUrgentCare , you’ll find the mailbox is full.
Next, after driving to the urgent care facility you found online, whose phone mailbox is full, you find you must deal with WalkInUrgentCare.
After creating an account and making an appointment, you realize that you cannot wait for very long, and you find that you cannot cancel your appointment (see the title of my review, but in all fairness, the developers might have been following the instructions of less-than-smart business people), and when you call (to be courteous) to cancel, you are back at that number with the full inbox.
WalkInUrgentCare is a waste of time and probably so is the urgent care.
