Referencing link not working

Can someone suggest me the best way to approach OpenRent, My current agent wouldn’t able to access the sent link and is unable to reach Open Rent via telephone…

Please someone guide me how to solve the issue, I have noticed it’s long standing issue which OpenRent need to upgrade to avoid tenant inconvenience. I have tried to call but no answer also sent an email and still waiting for a reply.

You will never get thru on the phone to speak to a real person , hence I am letting another place with an agent. Then I can talk to them.
