Thanks for your post - I am sorry to understand there has been some confusion regarding your bills.
When you choose to leave us, you will be billed as normal during your 30 days notice period; this means you are more than likely to get a "normal" bill before you leave us.
This will need to be paid in full by the due date - any missed or late payments will result in a £10 late payment fee and could impact your credit score.
Once your account has closed, you will then get a final bill around 10 days after your account has closed. This will show any refunds that may be owed to you for services paid for an not used. If the final bill shows a credit, this will be refunded back to you via a Cheque Refund - this is posted out around 35 days after the account has closed and we advise to allow 10 days for delivery.
I am sorry if this was not explained at the time of booking your disconnection.
I advise you and anyone else leaving to cancel your direct debit ASAP as trying to get the money owed to you by them is impossible, you'll wait 45 days then be told is in the post and to wait 5 day, which you'll do before contacting them again and again and be told again again to leave it 5 days.
Take a look at my thread, it's been 67 days since my contacted ended and I'm still being asked to wait 5 days for the cheque.
It's highly unlikely you'll get charged a £10 late fee since this is only added if your bill isn't cleared before the next one is generated. As your services would be disconnected before then it will just amend the last bill. The difference is you would need to make a manual payment to cover the outstanding amount.
If this amount isn't paid then that's when it would affect your credit file as a late payment, or a default if it goes on longer.
For others being fleeced this same way, please consider making a report to the Ofcom monitoring department. They won’t assist with your individual complaint, but by making a report you’re adding to the number of reports that might help convince them to hold this company to account for their practices.
