Bad service

I upgraded with them last month and I still haven’t received my phone but instead they charged me for a phone that I don’t even have yet and the consultants take you from pillar to post and they are so dismissive and I am always the one calling to ask if they have stock or not they have never bothered to call and give me an update about my phone instead the debit me for something that I have not received currently I have a good mind to just cancel my contract with them
