Hey Ajmfish,
Thank you for the prompt reply 
That's great they're coming this Saturday, I'm in on that day so I'd love to check back in and see how the visit went.
If you can give the Customer Care team a call on 150/ 0345 454 1111 and explain the time you weren't able to use the services, they'll be able to amend any credits due.
Many thanks and speak to you again on Saturday.
Ben
