Horrible pathetic useless customer service

The absolute worst customer service! Have been trying to do an upgrade for 4 weeks and they keep having excuses as to not assist. Our branch keeps telling us to call customer care and customer care keeps telling us to go to the branch just because they couldn’t do their job correctly and upload our details on the system when we took out our contract! I would absolutely not recommend them they are utterly useless! And they never care to assist and resolve the issue!
