I have a restitution review on the 31 of this month. I normally walk my payment in before the court date
I know the coronavirus has closed a lot of business, and info would be greatly helpful. I tried calling but the line is always busy.
Courts are not open generally right now. Only emergency matters. In your case, your restitution review will be rescheduled when the courts reopen and they should provide you notice. If you have not heard anything by April 20th, contact the Providence Superior Court clerk's office with your case number.
