Never Respond or Act on Complaints

So i got a response yesterday, saying im liable to pay because I signed for the product. Well your level of dealing with customers is very poor. I indicated that as I am not a technical person so really Its hard for me to differentiate these product but I knew from start how what I was looking for looks like. And I mentioned to the agent dealing with me that I want an ADSL rooter she confused me and I dont know how we got to the 3G rooter. Why would I mention 3G if I wanted ADSL? Your level of professionalism is poor how do you sort out something without going to the root of it. Bottom line I will not pay for what I do not want I called immediately when I received the 3G rooter to get it changed and I get the right thing. The fact that you took 3 months to respond to me wont make me pay for it. Its like you want to pin it to me and I will not. If this is not acted upon I will have to take my complaint to the National Consumer Protection. I will not get blacklisted for what I am not using or benefit from.
