Worst thing I have ever talked to

Worst thing I have ever talked to
I have made the changes and they took the payment because I made changes and than they didn t make the change for the flight and I m trying to get a hold of them but they are not answering I m trying to talk to them one of them said he can see the payment went through and he can see there was supposed to be a changed on time and date
But they don t know and they transfer me to aircanada which has nothing to do with this
Please don t book with them.
