Unable to call TPG from overseas using skype

[snv]

I've tried calling 1300 number and the local number with 02 area code, the message says unable to call this number from the service, however I was able to call these numbers last month from overseas. 

I'm trying to cancel account.

Thanks

Hi @snv, 

Let's have your TPG account details via private message for further assistance.

Thanks!
