Service please???

<p>I have been trying for 3 days now to get hold of someone to assist me with an sales enquiry seeing that I was interested in taking out a 24 month contract. I made several calls and hung up after more than 15min holding on. I sent several chat messages but never got a reply and I also left my number several times for them to call me back and I am still waiting. So can someone please call me???</p>
