Just to add...
This is what they eventually emailed me regarding deferment/arrears..
"Please be advised that the information that you provided is currently being processed and you will receive a letter in due course.
Also I need to make you aware that you currently have arrears on your account for the sum of £897.13 covering a five month period. Please know that failure to keep your payments up to date may lead to the following;
Calls and letters.
Further administration charges.
The account being terminated which leads to the loss of your right to defer and the cancellation of any age and time related loan closure dates.
The account being passed to an external debt collector.
Outstanding arrears could impact your credit file.
If you are accepted for a deferral, we can roll back up to three months worth of arrears therefore removing them from your account. Any arrears that are there for beyond a three month period will be not be removed and therefore still be payable.
I trust this is satisfactory, however if we can be of any further assistance then please do not hesitate to contact us."
So it's closer to £900 I owe :,(
Even if they do cut off 3 months it's still money I don't have...
