Unacceptable Customer Service

We have flights booked that depart on 12th December (3 days away). Due to the travel ban imposed by the US and UK, we are not able to travel. Travelstart have switched off their phones, they're not allowing comments on FB, they're taking 2-3 days to respond on FB Messenger, they take up to a day or longer to reply on Whatsapp. All their staff provide conflicting information. So far we have no clarity at all. We have no guidance on what is going to happen. This service is absolutely unacceptable.
