Bad Service or No Service!!

I received delivery of my modem on Wednesday 14 October 2015 and contacted the call centre to activate. No one was able to assist me and I was told a call centre agent named Tashreeq would call me to activate. I have called everyday since trying to activate my modem and have had no luck. Up to today I have still not received any call from Tashreeq to activate my modem. This evening I spoke to an agent that felt it necessary to inform me she was going out of her way to assist me. Which I don't think is relevant since I called in. This is a huge inconvenience since I use my modem for business and I am also wasting considerable time and money contacting the call centre, which takes forever to get through to. This is shocking service especially since before I took delivery I was called daily by sales. After sales service is shocking
