Disappointing customer service

I went to vodacom Herm**** on the 26 Nov 2021, arranged to get a black friday deal. The agent said that they dont have the phone but he will load the deal and once the phone is delivered we will conclude the contract. However a weeks later the agent phones me and said that he made an error and loaded the wrong deal & that head office did not want to reopen the deal. The agent than escalated the issues to another vodacom department, however today this vodacom department informed the agent that the deal will not be reopened(more than 2 weeks later), even though the fault is on vodacoms side. This is truly bad service, i the customer is being disadvantaged because of an error that a vodacom store made, which is really unacceptable, in the almost 20 years i have been a vodacom customer have experienced a lot of issues with vodacom, but this seriously take the cake. Really unacceptable customer service
