Pathetic Service

We received a kettle as a gift and because we had one we did not use it immediately,when I opened it I realized the kettle did not work.The unit doesn't connect and therefore the water doesn't heat up which defeats the purpose of a kettle.We then went to the store within the warranty explaining we don't have the receipt due to it being a gift .However you can clearly see it was purchased at Mr Price with the signature of one of the staff members.Instead of giving some solutions or ideas on how to fix the problem we were told the person should have given us the receipt and they have no intention of lifting a finger to help.I have dramatically reduced my visits to Mr Price because of the continued horrific service.I would just like to know what I suppose to do with a broken kettle?
