Can't make a call. Even to the customer services!

[#1]

Have been having issues with my phone lately, can't make calls all of a sudden, people who are trying to call me get straight to the voicemail. Tried to dial customer services - the same problem. Please help.

Hi there and I'm really sorry to see there's an issue with your line at the moment. 

Could you send me a PM (there's a link if you click on my username) with your username or land line number and I'll make sure that gets dealt with.

Hi, the problem persists. Have you had a chance to look into it please?

Sorry for the delay, I've just sent a reply to your private message.
