Poor service with Vodacom upgrade

App**** online for upgrade on 12 November, after browsing saw a better deal and cancelled same day. Re-ordered online again and received confirmation of order 30/11/2020. Called today 10/12/2020 to follow up when receiving upgrade, customer care advise order cancelled, gave me reference number and advised it is the previous order. I provided new order number received on e-mail as confirmation VODACOMONLIN-*** was sent to customer care to the upgrade department, agent tells me it was cancelled by the system, asked to order it again advised no longer available but should speak to the online order department, put me through to the online order department, went through to a voice csi rating, clearly no intension to place me trhough to the correct team to fix the problem that was not mine. No appology for the problem nothing for not informing or attempt to try and get the deal I have conformation of. Not sure what the purpose is for online ordering if it is not working. Very dissapointed with the service, been a customer for years... just poor.
