Still no signal

On the 10 September I made a complaint of the terrible signal at my house. Someone from Vodacom came to my house and assessed and my feedback from Vodacom was that they are working on the signal in my area. However, 2 months later and nothing has been done! Another excuse was because I have someone staying above me, however my friends who stay in the same estate that stay in a double stack don't have the same problem. Surely there must be some sort of aerial or antenna that I could get that will help with the problem!!! How is this not an option. I cannot work from home on my 3g stick and struggle to go on any sites or even go on facebook or other apps. I think this is shocking from a Vodacom that they cant even help in the meantime till they sort out their supposive \Area signal problem". Highly disappointed!!!!"""
