Profile Blocked and NO RESPONSE

I tried accessing my profile for the past 2 months now, and the error message states that my profile is blocked and I should contact the call centre. I have done so, three times already over the past two months and they just take my details down and tell me my profile will be working again the following day.<br> <br> When I log on, or try to log on, the following day, it's still blocked. They then said I must use the USD code, but it also says I am blocked. No idea why my profile is blocked. I am a dedicated AB customer for a long period now, my accounts have never been in arrears, etc.<br> <br> CAN SOMEONE PLEASE TELL ME WHAT IS GOING ON
