No response on online enquiry

When I send an online inquiry, whether the service provider can assist me or not, I expect at least to be acknowledged and a yes/no answer.

I sent a query to Eurovision on Sunday, 16 January. Today is Sunday the 23rd and no response.

I'm quite disappointed. I had my hopes up that they will be able to assist me, but if my business is not important to them, taking care of my equipment probably isn't either.
