Unprofessional service from Vodacom

I have previously put a negative review about Vodacom on this platform, today I would like further add my disgust and disappointment towards Vodacom and their pathetic service. I purchased a xiaomi smartbox towards the end of last year, and informed the store manager as well as the sales consultant thereof. I was requested to return the device and I was told that the device would be repaired /replaced. I returned the device on the 22 of March 2022, and I have still received no response from Vodacom in this regard since. I have been to the store on numerous occasions each time I was told that they were awaiting feedback from xiaomi. I am totally unhappy with this unprofessional service from the store. I would like immediate feedback from the relevant persons in charge as this cannot go on any further. Mrs N Husain
