Garbage network signal and no internet for 2 months

I have been having problems with my internet for the past 2 months, I don't have internet for more than 10 hours a day. I decided to call an complain, I received a call from support and they told me I don't have coverage and then I received an Sms that my query was closed. I use Vodacom on both my phone and router and I only get 1 bar, it has escalated recently and haven't had internet for 3 days straight and not get any help. I rely on Vodacom for internet for work and my business is really suffering and had to resort to buying data from another network so we can be able to work in the office. We have a lot of conference calls via WhatsApp with client's abroad and we haven't been able to work effectively. I love Vodacom but they need to solve this ASAP.
