Haven’t been able to log in to my account since September,wanted to pay my balance.Tried chat numerous times,told details don’t match. Told to re-register didn’t work.Have e-mailed, hasn’t resolved issue.Have had letters, texts and phone messages telling me account in arrears and getting charged interest and late payment fee.Phoned, on hold for 26 minutes,finally spoke to someone.Eventually in November was told the detail that didn’t match was date of birth,was asked to send photo of passport or driving licence to confirm date of birth refused to do this. Still received letters and texts wanting payment.Have told them I will pay what was due in September but not any extra interest as issue is with their system. Last week received default notice phoned again,was told that date of birth would be changed so I could access account still doesn’t work.Asked multiple times for copy of Septembers statement including on last phone call.Today received another letter telling me what the balance is with the interest to date.Have been a customer for over twenty years but never again.
