No network coverage

Am on Telkom smart internet plan... Must say it has been the most unpleasant 15 months of my life. The network coverage is totally unbearable. The past 3 months have been the worst am either on 2g or 3g network 90% of the time. In any area I go which I find very annoying to retrieve your network I will have to completely switch off my phone and when it comes back it will be for a few minutes then back to no coverage. My place Telkom coverage is none existence. But data is depleted like am always surfing the net. Can't even log an issue on your App Can't wait for this contract to end, am basically donating my money to you guess. Do something with your coverage
