Telkom sucks....

I used to love Telkom so much even recommended it to my family and but now since they decided to have their own company to roam on the network as been very bad. I missed important phone calls because the sim is constantly refreshing and there's no network. Do something about this soon before the 7 july before I port to another service provider, cheap data is not worth not having a way of communication. Also due to the network problems I had to lose out on my data expiring without me utilizing it because there was no connection.
