Life / Need Help Topping Up Credit On PLAY Phone. Code doesn't work! [2]

Hi everyone

So I bought 2 x10zl top ups for my phone on PLAY PL network, in the form of printed receipts. I am entering the codes correctly (tried several times) all I get is a message saying that I've entered a faulty code.

So, I want to contact their customer services but I can't find an English language number or email/form with which to contact one. It's understandable that as we're in Poland I shouldn't expect English speaking support, but a section of their website is in English so I thought maybe there's a chance.

Any advice from anyone?

Thanks
David
