I'm no lawyer at all, but my common sense tells me:
DO NOT SIGN THIS!Instead, take the first page, fill it out and at the end of the page, put your place + date + your signature.
Throw the second page away.
Then make sure, you can 100% proof that you have a confirmation, that they have received your letter.
3 methods come to my mind:
1. Fax. Be careful though, you need the sending confirmation you receive after sending and on that confirmation there should be a copy of what you have actually sent.
2. Registered mail, where they have to sign that they have received your letter and where you get the written confirmation back.
3. Not sure if this is possible in Switzerland, but in Germany you can go to a court and have them delivering your letter in person. This costs a small fee, but it's the strongest evidence you can get, that they have received the letter.
If and when you put the letter in an envelope, get someone who watches you while doing it.
Also, when sending the letter, also have someone with you.
Otherwise they could argue, that what you have sent them was not the refund request.
If they don't comply to your request, because of the missing second page, you'd probably need a lawyer who will open Bitmine's eyes on what is legal and what is not.
Again, I'm no lawyer, I cannot say 100% for sure if they are allowed to force you into new terms to receive your refund, which conditions where originally defined in their TOS at the time you bought the miner. In my oppinion they cannot. If in doubt, please contact a lawyer before you sign anything!
Edit:
Thinking about it, they cannot refuse your refund at all, if you do not sign the second page. Why? Because as long as you do not agree to their new terms on the second page, the original TOS applies, which says:
3.3 If, where permitted by these Terms, you wish to receive a refund for the goods, you will need to provide Bitmine with details of the source bank account or Bitcoin wallet number used for the purchase of the goods.
4.5.3 After the 61st day of late shipment, you have the right to request a full refund and we will pay you an additional penalty of 10% of the initial order amount, including shipping fees.
These are the rules that do apply. Nothing more, nothing less. Don't agree to new rules by signing the second page. My advise.
