Telkom network in Durban CBD sucks

Telkom network is terrible. Especially around Durban CBD. I keep losing network and have to manually select a network each time and within a few minutes of selecting the network manually it loses signal again. It is really irritating. I'm considering changing networks because of this alone. I work as a security officer in Durban CBD in Russel street and surrounding areas and my phone is all I have to keep me occupied and awake during the night shifts and now I have to deal with this nonsense. I am sick of it. You should really do better Telkom. You've been around a long time. This is totally unacceptable.
