Bad Vodacom Customer Service

I could upgrade my 1 contract from 1st of Feb 2021, after phoning them and finishing the upgrade, I only learned then they did not have the Samsung A21 in stock. I called back the 8th of Feb after I already sent an e-mail before then, to ask when will they get stock but got no reply, when I called I changed to another package, and they did not say anything about not having the Samsung A31 in stock so I assumed they had stock. Since today I haven't heard I thing from Vodacom, it is like they are ignoring my e-mails. I have never waited so long for a new phone at Vodacom after upgrading.
