Bad service

I logged a call to ask for help to cooy my data from an old to a new sim card. The call was closed as resolved having seen my sim swap complete (this just got me operational on thenew sim in a new phone). First bad point, not bothering to read my request, second then closing the call on a faulty assumption. I tried to respond to the email address on the bottom of the email to complain, only to find out that it bounced back. Third issue - please update to curernt if you are going to give me an email address. Then I could not find an email address anywhere on your site to send my complaint to, fourth issue. And lastly, number 5, I am on hold for ages in your call centre just trying to find an email address to get this all sorted.<br> So I am using my time waiting productively by putting it down here in writing.
