@ simonpimpernel It's not too late to send off an amended form - there's no deadline for getting your application to Erudio, but they do state under the FAQ on the website:
"It is therefore important that you return your completed form and evidence to Erudio before the end of your existing deferral period, to ensure that no payments are collected from you and that you do not fall into arrears".
This seems to contradict other info, where they say that you must continue to make repayments until deferment is granted, but I think this is aimed at borrowers who are currently paying and want to apply for deferment, not current deferrers.
Until Erudio receive the signed deferment form, they will insist that you haven't made a valid application, and can start demanding repayment. Surely the priority has to be getting deferment granted, then fight them over the changes to t&c's? If we do it the other way around, it will drag on for months (unless FCA/FOS intervenes), the 3 months for backdating the deferment will pass, and we'll have a whole new fight to get any repayments outside that period back (you could make this part of your complaint, so you get all repayments back if the ombudsman finds in your favour, but it still means paying Erudio in the meantime).
We have to take our complaints to the ombudsman whether deferment is granted before or after that process, but I don't want to give Erudio the opportunity to get their paws on my money, so I've amended and signed the form and will fight them over the t&c's if/when they grant deferment. I possibly wouldn't have done it this way if I hadn't read on the forums about what is and isn't working for others, but it makes sense to share and use that knowledge to help everyone through the deferment and complaints process.
