WORST NETWORK NIGHTMARE EVER.

I have been struggling with Telkom network since last year December, every time I try to call them my calls get cut off because of their network .I have tried to send email but they always bounce back . I buy data but it expires before I cant even use it. People complain that my phone is always on voicemail when its always but because of this stupid network I don't receive call. I have lost a lot of important calls and job opportunities because of this network. I cannot wait to change it and will stop anyone who wants to use it.
