I had problems with Eticketing for 2 friends tickets in Cape Town. In the end I claimed back against my credit card and got a full refund. Your contract was with Etickets not a 3rd party. Spesk to the bank you used to purchase the tickets.
Just to add a little warning on Etickets. They failed to provide day 1 tickets for Cape Town but didnt inform you until after play had started. I understand it may have been problems outside their control, but paying over the odds prices and not receiving the goods doesn't sit well with me.
Personally I'd avoid Eticketing like the plague. They failed to deliver day 1 tickets for Cape Town and 2 of our friends didnt get informed until after 1 hours play on day 1.
Tickets will go on sale via the cricket Lanka website.
I wouldn't leave getting tickets to the day of play, it may well be sold out before then. Book on the Lanka website and pick up day before, or as your hotel if they will sort them for you.
What an experience this would be, I'd love to be considered. Turn 50 tomorrow, played at different levels throughout my life as a pudding throwing bowler. Still involved now at local level playing in divisions 3, 5 and 6. Spent the last few years bringing on junior players.
As for Cape Town...
