Cancellation of contract

Please refer to reference 1- ********** ********** . I have requested for reversal of the upgrade. The consultant at your call centre confirmed that it will be collected by courier on within 4 days. I also wanted cancellation amount on my existing contract, which they said they cannot give as reversal of upgrade hasn't happened. I need this device to be collected immediately and cancellation figures to be given to me immediately. Call me on this number **********
