Credit Cancellation What To Do?

I ordered a laptop and financed it through a bank. The right of withdrawal from the bank is 2 weeks, the right of withdrawal from the store where I ordered the laptop is 4 weeks.

the laptop will only arrive in about 3 weeks. The cancellation period only begins when I receive my parcel, now the problem and the real question comes. I ordered the laptop with the wrong configurations, which I only noticed now. However, the bank's deadline has expired. How is it now
can I still cancel my product and reclaim the first payment?

Don't you dare to call the bank? We can't grant you the right of withdrawal!
