A technician didn't show up, and I cannot access to the webpage to check/arrange the order status.

Dear O2 staff,

I ordered a new DSL contract with O2 about 20 days ago and a technician should have shown up in this morning (05/11, 8:00-12:00), but he did not.

Also I cannot call the hotline because I do not speak English. I tried several times but did not understand the instruction.

I cannot check my order status, too. When I try to check, it always says
"Unfortunately, this service is currently not available for technical reasons."
My order number is CINAo2N02994896B.

Now I'm really not sure what to do.
I don't have any internet connection in my apartment, it is very inconvenient.

It would be great if you could help me.
