WORST COMPANY EVER

I upgraded a week ago and decided to cancel the upgrade a day before delivery of the phone. Consultant explained what I needed to do and followed all the procedures, asked for a reference number for the upgrade reversal and consultant told me to use my cell number as the reference. I was told that I could only cancel the contract after about an hour for them to process everything. Called 3 hours later and told a different story, now it took about 1 day to reverse and cancel the contract. Phoned a day later and told yet another different story, this time the courier had to deliver and I should not accept the package and that is how it will be reversed and cancelled. 5 days later, no delivery and yet again different story, now my upgrade is still effective, never cancelled and order still pending, as if I had never cancelled it and after almost an hour on line with the Customer Care, they drop the line and send me a sms to apologize and a different number to call. USELESS THE LOT OF THEM. It seems that they use that tactic to keep contracts to generate funds, how difficult is it for the idiots to cancel an order and reverse the upgrade....seems like rocket science for CELL C...
