Missed Full Payment Submissions - No internet

I have missed several FPS due to having no internet. Unfortunately, I submitted FPS once internet restored but it has stacked up the PAYE for the missing weeks leaving staff unable to claim benefits due to HMRC saying they have received too much pay. I then submitted a further FPS the next week as I didn't realise the problem the previous week's submission would cause so unable to send adjustment. HMRC and Sage are not offering any assistance - just bounce from one to another. Any help would be appreciated.

Hi,
If your staff were paid the several weeks in one payment then the information is correct unless you state they were entitled to the money in a previous period. If you paid them each week as normal then you will need to roll back your software and change the payment dates to show the correct dates of payment.
Thank you.
