Vodacom/Vumatel Internet connectivity

Good day I'm writing this on behalf of my daughter and I have to say every beginning and end of the month we have a connectivity issue with wifi/internet service. Last month we only had connectivity for less than 2 weeks. Today is the 3rd of June, since 30th May internet services are down. My daughter calls vodacom and consultants responds its fine on their side. My daughter pays for service yet vodacom they not doing anything about it. Not sure if they do follow up to check with what's happening with their clients. As a mother I have to say the service is poor and appalling. The black box all the lights are green, on the router the internet light flashes all the time. The thing I cannot tell if it's vodacom or vumatel so all I can say it's tiring calling vodacom every second day and nothing is done at all. My daughter does work from home and she does need internet to do her work. This is annoying, I'm disappointed with the service provider. As I mentioned I'm writing on behalf of my daughter, I do not have the reference number. I'm reporting this because enough is enough.

Your assistance is much appreciated because I've given up with Vodacom/Vumatel

Thanks Clarah ***
