Vodacom fiber cheats clients

Vodacom fiber is worst, from employees to fiber connections & gadgets, I am sure if employees on their call center are trained or what, at least there is one lady who did her best but also she did not finish her task, for 15 days I did not have wifi, which I called & made follow ups( Dec 24 to Jan 7th), but month end Jan the whole premium was taken from my account, I then requested for credit which was granted, only to find today again the statement for Feb is still saying the full premium, I am currently in the same problem of wifi not working since Friday the 3rd Feb until Today, mind you, I have been calling, making follow ups, which they make you hold very long time, I am using my airtime, buying data with own funds but my problem is that still on that they want to take the whole premium. Please note that their wifi will there and there be down, may be a day of 2 days which that I am not complaining but for 15 Days? or currently now for 7 days? Is this fair for me as a client? why do I have to pay full premium for services not provided for 15 days or 7 days ? why do I have to buy data & again pay Vodacom fiber ? why is your call center people playing with your own clients? acting as if they are helping whereas they just making one to calm down? I need my credits, I will not pay full premiums for this. Can someone please assist me
