Vodacom signal dispute

I have been battling with Vodacom for six year regarding signal in at my residence. As a incident administrator working remotely is required for after hours support as well as for standby. Unfortunately I am getting escalated at work for my phone being off when that is not the case I made multiple attempts to have a signal booster installed with no luck I’m paying 1400 a month for a service that’s not working and they won’t help me I have to buy my own signal booster according to them because it will cost them money to give install one for me but at the rate things are going I’m going to lose my job because of the signal issues and then how will I pay them monthly. I am going to ICASA as this is a violation of the consumer act. I’m hoping they can assist me in resolving this issue
