Cancelled Upgrade being forced through

I have requested an upgrade cancellation that I took with Elite Mobile,I took did the upgrade on/about Friday the 16/10/2015 which I then cancelled on Tuesday 20/10/2015,the Elite consultant Angelique told me that she has sent a Cancellation e-mail to their cancellation department.I also spoke with Veronica who adviced me that I should not accept the handset as Vodacom will cancel the upgrade as soon as the Handset if returned to their warehouse.On Thursday 2015/10/22 I received a call from RAM confirming my refusal to accept the Handset.Since then I have called Elite Mobile several times to ensure that the upgrade is cancelled,when I request to speak to a supervisor/manager they just transfer me to a line that plays music and then goes dead.I consider this a delay tactic which is aimed at having the 1st installment collected against my wish,which is ********.I want that upgrade reversed immediately.<br> <br> If the cancelled upgrade is forced upon me as I was advised by Vodacom that my account has been \migrated 2015/10/26"against my will"
