Bike lock issue

I lost both keys to my bike lock. The bike is located in my house, and I hung the lock inside the cable, which is tied to an old door handle. (It is in the common area and I cannot break the handle, I am a tenant). I need someone who has a heavy-duty blade or bolt cutter to cut the cable (the Kryptonite lock is not involved, luckily and only the cable should be cut. I used a hacksaw but it was not strong enough. There are strong metal threads inside the cable. The cable is exactly like the one in this pic). Alternatively, if anyone has a sort of master key to open the Kryptonite lock, it would work as well to get the bike free from the door handle. The task is super easy, and if one has the tool, it takes no more than 5 minutes.
