Some of the worst customer service - more than 24hours for esim activation!
Some of the worst customer service. Purchased an esim and it took more than 24hours for them to sort out the activation. Every time I message or call them, it's the standard reply that their team is working on it and will be done in the next 2-3hours. Keeps repeating the same thing over and over again! Can't even bloody cancel my order as they just ignored my request and continue to ask me to wait.
