No support!

I have been without Internet access for 7 days now. I first contacted the call centre on 23 June with the problem and was advised to go to one of their outlet shops to teattest my modem. Which I did and it was working perfectly. The young girl that assisted me was very friendly and helpful. I got back home, plugged it back in and still no connection. I logged a case on 25th and I am still waiting for a technician to come out. I have followed up 3 times now and all they do is say that they are escalating the matter. This is our only way of communicating via Skype with my husband as he is stationed in Nigeria. We are extremely frustrated!
