What a joke. I am sorry you have to deal with that.
Repairing that won't be too bad. Chain link is repairable. Buy a section the same height and width you need. A single wire will twist up and out as you spin it. Spin a wire out on both end of the bad part. Put the new piece in place, and spin a wire back down into in to mend the new and old pieces together. Going in will be tighter.. so I run a strap across from the old sections and pull them closer to put the new section in.
