Query: Multiple problems within couple of months...

The adapter seemed like a great value and I was delighted to find it at such a bargain price. When it arrived, it looked good and also worked well initially. After about a month however, the plastic casing on the cable that connects to the electric outlet started sliding somehow exposing and causing the wires to short. I had an extra cable so I changed it and it was back to work for another month. But recently the adapter has stopped working completely. There is no visual damage and I took it to a computer repair shop to check for any cable damage etc. but there was none. I have no recourse but to pitch it and perhaps buy a good original one from Dell.
