Ais Roaming In Cambodia - Huge Time Overcharge

[Smithson]

Recently I visted Siam Reap for 4 days and made 4 call on my AIS mobile. I kept the calls short as I didn't know what the charge would be.

When I got the bill I was charged for 4hrs, but I reckon I spoke for a total of 15-20 mins. My GF agreed, remembering that I had mentioned the unknown cost of the calls and kept them very short.

Has anyone else had similar experiences? I don't suppose there's anything I could do. The cost isn't that great, but thought it'd be good to warn others.
