Hello bbob
First of all i want to say the following because what you say it's not truth
You can call GT SIM customer service for free even if you are not customer
On the main page follow the link
NEED HELP
then you can call them for free.
In my post i just write my experience with this company i never tell that it's the best in the world i just say it's a
good deal for the price you pay and i'm not working for them.
If you know any global sim company with a nice customer service tell me i will follow you, but for sure if the customer service is good you will have to pay more for this service and this will be useless.
If i want a good service but a high price i will keep my actual cellphone company SFR, with them when i'm abroad the service is almost perfect, but not the roaming rates
Once again if cangia wants is money back the only way that i know it's to try to get them (call or email) again and again
even if that means for you that GT SIM get a bad customer service (for me too
).
After that if this does not work you can try to use the credit card insurance to try to get your money back, normally should work.
