Once upon a time I purchased a SIM card and transferred my CDMA number onto the new sim card. This was a sim card only purchase. A week later I purchased a XT mobile only. I paid the full price for the handset over a 12 month deferred payment scheme. 

Now because of reception issues and poor pricing plans, I moved my number over to vodafone.

I then found on my next Telecom bill a whopping $800 on it for the full price for the mobile I purchased on deferred payment (which I had been paying off happily for 2 months prior)

Now even though I get charged on my Telecom bill for my mobile use, and even thought I purchased a mobile outright (not associated with a number) it appears because I transferred an XT number over to vodafone that was on my Telecom account, my account was closed! so all outstanding deferred payments must be paid.

I went into the retail store and even spoke to the regional manager who said they are different from telecom "One Telecom???" and when I said it appears on the same bill she kept saying that it is different?.

She then said because the number was transferred away that my account was closed. what account? it appears my mobile account because you cannot have a telecom purchased mobile charged to your Telecom account because it is not the same thing?

In any event, I advised I bought the hardware separately where they said that it had to be assigned to a number before it could be deferred.
I then said they must have used my XT sim (purchased separately) and assigned that to the phone I bought. She agreed. I said that no one advised this was happening OR the fact that if the number was cancelled or moved away that my deferred option would end. She then said that we surly can’t expect them to advise all users that if they move numbers away that this sort of thing would happen!!!! when asked why she said it would be because users would not sign up.. can you believe this. Now I am stuck with sucky terms and conditions which they don’t want to tell people about.

They were very unfriendly and I just can’t believe the lack of service I got.
My next stop is to go higher as we just can’t afford to pay such a large amount.

So my advice to you all is to watch out for this as it appears they are not so forthcoming in regards to advising of all the traps out there.
