Pathetic useless excuse for a company

I have upgraded my LTE contract in January, it is now April and I am still waiting for them to deliver my device. I am paying for something I do not have. I have called their call center department, sales department, spoken to them on social media (which is pathetic) as well as went in store and no1 can assist me. I am bouncing between those departments for 4 months now. Each time I get told the delivery is being sent but No1 can tell me where the hell it is. Watch out for these things, they make you pay for a service you are not getting and no1 who works there knows a thing. I can't cancel because I have to pay them a cancelation fee which of course they once again benefit from. This is a mess up on their side and not assisting me or ignoring me is what they ignore doing.
