CONTRACT CANCELATION

Was due for an upgrade 18 May 2022, tried calling to cancel upgrade beginning of April and was sent from pillar to post advising that it should be 30 days before the contract expired with the Easter holidays by the time I got through to Cell C I was already going to pay for 1 month. I was then contacted by head office convinced to upgrade which I ended up agreeing in that was the 11 May 2022, to this date I have not received my new device. CELL C I WOULD LIKE TO CANCEL THIS CONTRACT THAT I HAVE HAD WITH YOU FOR THE PAST 14+ YRS
