Vodacom - Severe Signal problems

I have been experiencing severe signal problems at home for the past 2 months. I literraly dont have any signal to make phone calls, msg or use the internet. I have reported the problem with Vodacom and the agent told me that Vodacom has plans for the new financial year to erect a new signal tower close to my home - however this will be somewhere in 2016. I had an incident at my home on Wednesday 11 Nov and were not able to call security or the police as i had literally no signal to make any phone calls. This is totally unacceptable as i am paying for a service (at a premium) which i dont have. I am insiting in Vodacom that Vodacom terminate my contract early so that i can move over to another service provider that will be able to provide service and signal when required.
