Shocking unaccountable service poor client service

I am eligible for an upgrade on my vodacom contract and received a call on 09 march 2021 at 10.29 from number *** and his name was musi from vodacom retentions .we discussed various options and phones and then decided on the A71 and I even told him I did not want the black one .call was concluded and he still stated I would receive an sms but nothing to date.i called vodacom today and the one agent imp**** that I was lying and this did not happen and the other one mpho from upgrades was more concerned about defending her colleagues than losing a long standing client. I asked her to escalate this matter however she did not appear to be wanting to do this st all. I am highly irritated and annoyed that I did not even receive a call back from no one and only came to my attention today that this fone is discontinued. Absolutely shocking client service and and wonder why I am still with this *********** cell provider for so many years and have to put up with this nonsense.i would like the call pulled from your records and listen to exactly what was promised to me as now there is no record of an upgrade on the system and I am the loser at the end of the day. No one is held accountable for their actions.what happened to the client is the midst of this terrible service
