Extenders and return of equipment

[Sally__]

I have 2 issues:

1. I paid £7.20 postage to return my old extenders when you installed a new one as a postage sticker wasn't in the box 

you've sent me reminders about this and I've tried unsuccessfully to contact you

2. since you replaced my extenders, the quality of my broadband has plummeted 

It was brilliant with the old extenders which broke

@Sally__  Returns posts is free if you used the corrfect process for returning equipment https://www.sky.com/help/home/broadband/sky-broadband-equipment/return-or-recycle-equipment/articles...

Did you include any account number with the return? If not SKy won't know who they were from.
