Telkom Opps manager' bad attitude.

Telkom's Opp manager is rude and not listening our complaint. 7 days later and the problem is even worst. Drop the phone twice in my ear. Does not listen to what I am saying and tells me in a ****y way to read my manual. Tells me problem lies with the device, but after having it tested by the CC and testing 3 other devices, he still said that the device is the prob. CC confirmed a faulty line. This guy has a bad attitude and are not supposed work with clients. Please replace him with someone with the necessary skills. He gives Telkom a bad name
