They promise to escalate the matter, to date there's no solution Noisy call centres No feedback from the call centre, even after they promise to do so! No method of escalation. No cancelation process to the service Noone seems to be able to assist The only point of contact is the call centre, which seems not to have solutions to the customer's problems.
