VODACOM ONLINE ORDER CANCELLATION

I lost my phone and called Vodacom online for an upgrade as I am already due for one. The "confirmations" department called me ONCE on a sim that I use on a router after I had asked them to call me on an alternative number. 3 days later I followed up and decided to cancel the order as it would be quicker for me to get a phone from the store and now, I am being transferred from post to piler and instead of cancelling the order I am being told that they will write a note on the system for the confirmation team to give me a call! This is really frustrating because the number that they are calling is in a router and does not recieve calls at all.

I tried looking for solutions on Vodacom's websites and they are all broken.

Can someone please help as I need a cellphone and the "confirmations" department will never get hold of me.
