No positive response received after email was sent

I Have never experienced such poor service with an upgrade of my cell phone, I have had endless issues with Telkom personnel. I sent a lengthy email to Telkom detailing my experience of which i had a \ manager"eventually respond to it after 3 weeks. He too promised me items of which he now also does not exist. I find the service aspect of Telkom extremely pathetic and would like a proper manger to respond and let me know how they will rectify the wrong<br> """
