When I spoke with the sales at Wind a week ago, he said that I could get a prepaid sim card without signing a contract. However, he asked my driver's license and asked me to sign some documents. In a brochure there is a mention about a 15-day return policy that if you are not happy with the phone or service, return to the store. I complained to the sales about the poor connection the next day I got the sim card. He said that there is no refund and if I don't like the service, I just don't top up at the end of the 1-month period. I double checked the document he gave me. There is a mention that the commitment period is monthly and the first payment due date is next month. What is that all about?
