Unhappy customer

I did an upgrade with the upgrade center over the phone on the 13 January 2022,however I wanted Samsung S21 FE 5G a it has a special of free Tablet for R499. The agent that assisted me Mothusi argued that the special is on S20 and not S21 as I have confirmed that I have received a sms about the special and I have also seen the adverti*****t on TV and he then proceeded with the phone to get to me, 18 Jan 2022 I received the phone and called them regarding the free Tablet and I was told by the lady of online sale that the adverti*****t is false and will be removed and I must ignore the sms as well.i got a call from Keith from Vodacom who the told me if I have been assisted with the Tablet and I said no and he confirmed that they need to sent me a Tablet as the special running and he told me he will call back the following day which was then the 20 Jan and he never called back. I called call center and I was advised to call the after sale department which I did and I was told the device will be collected and sms with reference will be provided to me. Friday the 21 Jan I lodged a complaint and Thato Makoti acknowledged receipt of mail and that he/ she will be in contact,until today 25 Jan 2022 no call from Vodacom. I called the call center en I am told I must wait 7 to 14 days for the phone to be collected and I asked that because I have 14 days to return this if I'm unsatisfied what will then happen if its more than 14 days and its not collected Mmapula from after sale department said I must just wait. Vodacom this is really unprofessional .as a paying customer I need to be treated fairly and with respect. Can the matter be resolved soonest
