Currently in Singapore and 1 day into a $19 roaming add-on that I bought when I landed in Sydney on the way here.

As per image below, this worked as expected in Sydney (no charge for txt's) but since arriving in Singapore I have been charged casual roaming rates for calls and txt's but interestingly (well, fortunately) not data.

Something badly amiss. 

How do I get this to stop and how do I get the charges reversed?

As can be seen in second image add-on is showing as active but only the 7 txt's sent from Sydney and data usage have been deducted.  Not the txt or calls made or received here in Singapore.

Singapore is listed as one of the countries covered by the add-on.

A couple of weeks ago I bought the same add-on when I landed in UK. That worked fine for the 4 days I was in London, then 3 days in Bermuda.

But this time things seem to have gone haywire.

One oddity.  In my Vodafone account, this is actually showing as three active $19 roaming add-ons, all displaying the same info as in the image below.

Any help appreciated.  At risk of running out of credit in my account if this continues.
