"Have tried to, no response, have also sent email, that's why I was asking if anyone else has contacted them."
Apologies then. Many people tend to expect somebody else to do things for them.
May I suggest you should have started with something like; "I've tried to call them, but has anyone else..."
We can only guess they might be inundated with enquiries. If you left your contact details, they do actually have a good track record for returning calls.
