Poor service

On the 24th January 2022 i called *** to upgrade my line. We discussed all the options and decided on a deal suitable for me. The deal was approved and was told it would take 3-5 working days to be delivered. Around the 2nd Feb 2022 i called again and was told they had no stock, i was never provided with alternative options or a work around as this is an inconvenience to me as i am still waiting and no call from Vodacom to say what is the hold up. I am very disappointed as i have never experienced this kind of treatment. I have been with Vodacom for a long time and always upgrade or take new lines and have never had to wait for this long and without any explanation even. Vodacom please tell me what i need to do now as i am tired of calling and i do not think i should be the one making follow ups.
