Horrible service such an inconvenience

I called Vodacom on the 30/10/2024 anround 3pm and received a quote for R2049.00 per month for 24 months for an iPhone. I asked the agent Nitesh Singh to hold on to that quote and call me back at 11am the next day so we can finalize and he confirmed that he will hold the price and call me back. I then called back on the same day at 4pm and advised another agent that I would like to proceed with the deal and the agent advised that she will get Nitesh to call me back on the 30th, which he didn’t. The agent also confirmed the deal and advised that it was accurate. Nitesh did not call me back and I called again on the 31/10/2024 at 3pm and asked Nokuphila tembe to assist, but she is now saying it’s a 36 month contract. I spoke to her supervisor Virashni and I was advised that the deals change daily and they cannot honour what Nitesh provided. This is ridiculous that I am loosing out on a deal because Vodacom staff did not call me back or advise that the deals change daily is only valid for 24hours. How can a quote only be valid for 24 hours, surely that cannot be the case. Now I have to wait for the recording and further delay my upgrade. This is such an inconvenience and there seems to be little care about customer service.
