Very angry customer

We have had an LOS light since last week Monday today marks 11 days without internet. The call center doesn't answer calls. The WhatsApp channel takes at least 5 hours to respond. When you FINALLY get to speak to an agent, they keep on saying the Technician is on the way. Today all of a sudden the internet started working for 2 hours. The LOS light is back again. I strongly believe that our credit is also going to take 7 months before they approve of it. If no one comes to fix this tomorrow, I'm not sure I'll still be a customer. That's that
