I subscribed and then terminate one week after being within my withdrawal period.
They sent me an email as well as a letter to tell me that they would reimburse me for the costs that I had related to this insurance because it had not had time to take effect. Today I realize that a direct debit will go to my account. To reach them is very complicated.
I have terminated because of serious advice faults. The guarantees exposed on the phone were not the same as on my contracts plus the fact of not informing me correctly of my rights, and other things besides. You should know that this is only a post office box in France nothing more.
And given the comments, no desire to stay at home and trust them.
