All fascinating comments. The only issue I have is I purchased a SIM card one day, then purchased the mobile, outright full price (yes on deferred payments) a few days later.
As I was buying the phone outright with no comments or discussions around a mobile number I was under the impression this was an ok thing to do and did not know there was any tie into the number I had transferred onto an XT sim the days before hand.
I understand that they probably did this behind the scenes but I was not told it and thus why I am upset about this whole process. I understand the logic behind it all but just feel grumpy about it as all I did was buy a phone on day and was told I could defer the payments onto my TELECOM account (which I still have and which I got billed all mobile data/calls etc...) on.
