Intellicell

So I have had 2 phone contracts with Intellicell, my proplem is that my device gets controlled by their app, skip a payment and they switch the device off. But that is not the problem. My problem is that a month before my contract was expiring the phone suddenly went off and then I had to get a new contract because I could net get in to the phone after factory reset. The phone does not recognize my *** as the owner. So I had to take a upgrade and ordered a tab on the 7 October, 4 weeks later I'm still waiting because they don't have stock, I then contacted the help desk who told me that they have another tab I could take, so I was happy with the second one, until they told me they also don't have that one. Then I told the lady I was just send a mail to confirm they have that one. Really this was for school and a birthday present at once but they mest up the whole flow. I then asked her why do they advertise stuff they don't have, I then asked to speak to a manager but conveniently there was no one available and no one can give me a satisfactory answer. I mean, come on!
