TymeBank service is non-existent

I spoke with the call centre last week Friday 16th April @ 11:55am, as I could not change the default phone number on my account at any of 3 kiosks. (There will be a recording of the call at this time). She spoke with another department, and then requested the new number, which I gave her. I was told this would be done by them and would take a couple of hours. As of the date of this post, the old number is still on my profile. Emails to *** are ignored.
