Clay Sim — Please ensure that you have the right sim delivered to you before using it

I was travelling to France and this sales guy from Clay Sim Cards delivered an Italian sim card inserted in the France pack. What pains and frustration i had to go through my travel, first with the wrong number, hardly receiving any signals and calls and then finally switching to my Indian number and having to pay a crazy bill. The first and the last time that ever anyone used it from my company and my social circle as well.
