Upgrading me without permission

STILL NOOO feedback from MTN. A few weeks ago I went to upgrade my phone. Upon the final stages of upgrading i was informed that there is a R150 \upgrade charge"and I refused to pay it AND after waiting 10 minutes for the \""time delayed safe\"" to open - the staff found out that they DONT HAVE STOCK of the handset I was interested in.<br> <br> I asked the lady to CANCEL the upgrade. I went on webchat with MTN and they told me I can phone them to \""waiver\"" the R150 (mmmmmm - wonder how many pay this R150 and not knowing they can phone to waiver it)<br> <br> Last week I went in to upgrade and the system showed that I can only \""change again\"" in 3 months time as I have \""upgraded\"" as per their system (when I specifically asked her to CANCEL it). I have been phoning and the branch has been phoning every day and the status is \""we are busy with the query\""<br> After being a customer for 20 years (with the same phone number) - this is the second time in 4 years I have had to deal with this incompetence from the MTN side - every time I Upgrade. It seems like \""loyalty\"" means NOTHING to them. """
