I signed up for PlayStation Plus 30 days trial over facebook and received an email last night. But the voucher code is "None Available"
Can someone help me out please? Thanks.
Sorry for the extremely delayed response regarding this issue.
You will need to contact Facebook support about this and request alternative codes from them if possible.
Bear in mind, if you have previously used PS Plus or even had a trial for it, these codes will not work. They are only meant for first time users.
