I've previously used my 3 credit balance to pay for items through the Google Play store. Following prior problems, I had thought the issues were resolved but yet again, despite having credit balance, the 3 payment method has been rejected by Three/Google, at first due to exceeding the payment limit (€60 pm I believe) , which I haven't exceeded not nearly, but upon repeated attempts, the reason given was 'payment method declined'. This issue occurred after the recent update of systems and is yet another annoying and frustrating error that prevents me from using my credit balance. It is unacceptable, and if 3 advertises that we keep our credit then they should ensure that we are able to spend it using what was a valid and convenient service via Google Play Store. I noticed that others have the same issue yet haven't found any solution or explanation on behalf of three.
