Bad bad service of Cell C

Good day I have requested for an upgrade Yesterday 26 March with Cell C after the upgrade I have notice online there is for the same phone for R49 more a VR gear headset. I phone in and request for an upgrade change, the guy told me I must wait a day and phone again next day to change it. I phone in this morning They told me I have to talk first to cancellation department and cancel my order. The Cancellation department have canceled my order and ask that I must phone the upgrade department. I phone the upgrade department they say my phone is already send out I need to wait 2 days for them to send phone back and then only can order again a new upgrade. This is really so stupid planning and service of Cell C I will cancel both my contracts with them and also let my parents cancel there phones with them so in total because of there bad service they will lose 4 contracts.
