I ported to 3 bill pay yesterday and now do not receive any of the critical texts from banks and Apple that allow me use my cards online. Have raised a ticket and tried to escalate but have been told 3-5 days is the time it would take before it can be prioritised.
I can prioritise my cancellation after 20 hours with three if this is how you deal with service issues. Just to be clear, I cannot use any of my bank services as I have 2 factor authentication setup on them all and I am not receiving any texts from automated services for some reason.
I plan to go back to the three store to hand back your phone and cancel if this is not dealt with sooner than late this week. Awful start to your service.
