NetBet Casino - Account not credited

I used the pay by phone bill option and topped up my o2 pay as you go phone with £20 worth of credit clicked deposit on the casino entered £20 as the amount to deposit then I inserted my phone number and pressed send, the casino sent me a text asking me to reply with the letter Y so i did then i on my phone appeared the word error? I check my balance on the casino and it was 0, I then proceed to check my balance on my phone and that was 0 so the money was taken off. I contacted the casino and sent 4 pictures of the message i received from them that was yesterday 05/08/2015 at 5:10 its now gone 24 hours and all I have had in response is an automated email saying they will deal with it as soon as possible. Live chat have tried to be helpful but all i get is "when the department have sorted the problem the will email me". This is the first time i tried to deposit too! please help

Just had an email from them around 4:28 asking if i had a transaction ID when i clearly said in my first email to them about the problem that i didnt get a reply when i topped up using my phone only an error message appear this casino is a joke

Dear Manlikechris,

As you informed us by email, it seems that these £20 have been taken by o2, not by Netbet.

We are happy that this has been sorted out but we would kindly ask you to confirm this here as well, on Askgamblers, in order to have this complaint closed.

We are doing our best to offer a great service and hopefully, this will be reflected in our members' posts.

Thank you for your understanding.

Best regards,

Melanie

Not the casinos fault o2's as they took the £20 after i topped up and didnt even message me so i didnt know it was taken thanks!

Complaint is rejected. Player didn't have problem with a casino, but with a deposit method via telephone bill.
