The travel service has been running a reduced timetable in line with government guidelines, but as more people heed the self-isolation advice, they've decided to suspend all coach services.
Services will stop from 11:59pm on Sunday, April 5.
They said: "For those of you that have an upcoming journey with us before May 31, if you would like to amend your booking, you can do so for free, for travel any time in the next 12 months.
"There is no need to contact us straight away, just complete our ticket amendment form before your original outward journey and get back in touch with us when you’re ready to travel again.
"If you do not wish to amend your ticket to another date, we will fully refund you. If you haven’t already done so, please complete our refund form and we will process your refund within 28 days."
The situation will be reviewed when the lockdown has been lifted.
