Also had my account closed this week. It was immediate with no warning. I have only placed 2 orders in the last year, one of them this week and not yet returned. I kept 2 items from the last order. Had to pay for my own postage to return despite keeping enough items over the £40 limit. Contacted ASOS to ask for further details on how I breached policy and if I could appeal. They replied saying they would no longer respond to any queries from me and just hung up. Horrible. Feels like something is going wrong at ASOS. Would be very wary of placing any orders with them even if you can access you account.
