Billing

I have done a lot upgrade in July 2021 and have also traded in my Samsung and was getting charged for 2 handsets, This was done at the blue route store a manager named Ebrahim Hardien was assisting me for more than e months the issue was not resolved in January 2022 I called every single day tge Manger does not respond or call after numerous attempts he then calls and said he will give me a refund for the last 6 months including January and from February I will not get charged , February a new invoice/ bill comes with 2 handsets charged, I called again every single day and called vidacom head office spoke to a team leader Thato Kgetsi there also promised to call and also assist no feedback. Back and forth I need my billing to be sorted , I am very frustrated with this level of service
