Fibre and Vodacom p

I'm experiencing endless problems with fibre supp**** by vodacom. I've made numerous compliance and three technicians on three different occasions have been sent out. "Fixed it" , wifi worked for about two days without dropping signal anywhere in my house. Then it all goes back to lossing signal. And it's not the download speed, the router doesn't even go off, there's just signal loss across all my devices connected to the wifi. Maybe there's a Vodacom or Vumatel Poltergeist. When asked to contact Vumatel, I did that as well. I've been a loyal vodacom customer from day one, and I've never changed to any other service provide, but maybe I should really reconsider my varying options. Vodacom you guys don't deserve my loyalty. Thank you Vodacom for becoming just like the other useless service providers, who talk a big game, but don't live up to the claims.
