No assistance at Vodacom after I returned phone with technical issues

@vodacom am so ****ed … my phone (Hisense H50 Zoom) was only 8 months when it went totally off and looked bloated and was unable to charge…instead of allowing me a new phone it was taken to the repair centre 19 Dec 2022 I was told it would take up to 21 days. Since that day I don’t have a phone… first they were waiting for parts now waiting for credit. It is the 3 March 2023 I still don’t have a phone. I have further more contacted them on social media and made as if they were assisting but still left with no phone. I was called by Vodacom the week before last week and I was told I can go get phone at Midland’s Liberty Mall Vodashop but when I got there they said credit has not reflected I must go back to Galleria… bare in mind they are the ones who asked where do I prefer to collect and since I am in PMB since mid January I requested Midland’s… I then spoke to Vodacom on Twitter and told them what had transpired … they then told me that credit could take up to 14 days to reflect …this was said on 24 February 2023. Vodacom last updated me when the phone was in repairs on 12 January 2023 after that I have been running around like a headless chicken at my own expense trying to get assistance in getting the phone they promised to give me credit for..
