Extremely poor service delivery

I wish I could rate them -5 stars. I have been struggling to upgrade one of my existing contracts since 3 August 2022. I still have not received the phone and the people assisting me since 12 August 2022 since I started to enquire are either rude or clueless as I have not yet received the phone. Today their system has been offline since 8:00 this morning with no hope of a solution. Every time I phone there is a new story. I have updated my residential address about 20 times since the 3rd of August 2022 and it is still the same as the old one. I am not a happy customer.
