Looks for CO2 refill paintball tank

[nevermind]

Hi everyone, i'm new on the forum so i searched for existing topics and found only one related to soda stream and CO2 refill. Yes i have a soda stream machine with a paintball tank and the adapter (all this purchased on ebay). I would like to refill my paintball CO2 tank in CO2 to use with my soda stream machine. I have try petro and Esso stations (no success, they do not provide CO2 refill) and i also called the Paint ball park in cham am but they told me they use "Air" to recharge their paint ball guns tank and i think this will not make the bubbles i'm looking for to make soda...

Any help or info on where i could have my CO2 tank refilled ? For info the small tank looks like this :

Thanks for your help !

Well, after long research i have finaly found the contact of a company which delivers dry ice at market village 3 time a week in front of the swensen ice cream shop. The number to order is : 084 752 6697

You need to order 24H in advance even for small quantity (i usually order 1kilo) and i think you need a thai speaker to make the call (my wife called so i don't know if they speak english).

Price is 30 bath for 1 kilo
