Poor after-sales service from Vodacom

I upgraded my phone on 1 June 2024. After spending a few days having to follow-up on the status of my upgrade, my phone finally arrived. As part of the upgrade Samsung is running a promotion where one is able to get a pair of Samsung buds with the purchase of the new mobile. When I submitted my tax invoice to Samsung they discovered that Vodacom entered the wrong IMEI number and requested that Vodacom reissue a new tax invoice with the correct IMEI number. It sounds pretty simple hey? Well, not when you are dealing with poor after sales service. One of their consultants, Lennon sent me a poorly written email in which he gave me a ticket number: https://cbuadmin.coactivate.co.za/helpdesk/tickets/240225 and merely said I should follow up on Monday. This I did and neither he nor anyone else responded. And in the meantime I run the risk of missing the deadline for the Samsung promotion. This is poor after-sales service!
