As I already wrote in your other thread: If you were due to return the Router at the Begin of 2020 -and there has been an invoice & initial deduction in July for the router, it's now -in October- much too late to just return the router.
It would've been your contractual obligation to return any rental devices in time -without any further "request" -and- at your expenses. If you have not done so, you would've been charged the price for all the devices not sent back in time - in case of an EasyBox router 69,99 €. But as you charged back the invoice, you'll now have to pay even more money -the initial sum, the chargeback fees and -as it's now moved on to a debt collector- their additional fees and their interest rates as you are more than due to pay the (initial) invoice.
And as you didn't answer to @Andre s and @MarvinRo s requests in time, it's only getting worse. So I really doubt that the whole process can now be stopped and reverted back if you'd only return the router - as there have been additional expenses already made on side of Vodafone that only relate to your actions by not returning the router in time and charging back the invoice without further notice/resolution.
I'm afraid that you'll definitely have to pay the whole amount - and with each week passing, it'll become more - and that returning the router won't help you anymore.
