Horrible Company

So after a year of working at this company I just quit because I found another company thats waaaaay better and pays better.. and my last day was yesterday and I told HR I will let them know by the end of the day if and when I can come in to return the iPad and get my last paycheck and I just looked and they deactivated my work email so I cant even get in contact with HR or anything to know when to go. Mind you, the office is in another city so id have to drive out there.

If they want the iPad should I just wait and see if they try and contact me a different way? Because they haven't and im not going to drive out there and end up not getting my check or end up missing a step or paperwork from HR that need to be signed. And im lowkey kinda stubborn and dont wanna call the office.

This company has treated me like trash and im shocked at how unprofessional they are. There was even a BT in the company that SA a 3 year old plus other potential victims so im washing my hands with them for sure.

What should I do?
