Hi wow, I'm sorry that happened to you.
I would check to see if you can return the item as it likely wasn't packaged sufficiently. But also is there any insurance give that the package was shipped by a a major carrier? They usually carry some ins on all packages. I would try that avenue first.
If all of that fails you can talk with the customer and maybe work something out and you may be able to have that fixed. Or fix this your self with my assistance?
If you are handy and have some tools and a meter I will help you go further if that will help.
Otherwise check with the seller about the ins or the shipping company, even the US PO puts some ins on all packages.
If you have any further questions for me please feel free to ask me thats what I am here for ;-)
We will find some way of resolving this without you having such a loss.
Please rate my service kindly at this time, so I can stick with you until this is all worked out with the best possible outcome. In addition I will send you phone service request form. If you accept that I will call you to discuss your options on this unit. If you don't want to talk on the phone please decline the offer but if you do accept that please send me your phone number so I can call and lest to best time for that as well.
Once again I'm sorry you have to go through this.
Have a great Sunday!
