Terrible service and refusing to refund

<p>We had the above mentioned company install wireless internet by my residence. After 6 days where we basically only had internet service for 3 of those days, I contacted Nicholas to cansel the service. I phoned him and asked that they come collect their belongings and refund me, he agreed and they came and collected all their belongings. I have since sent Nicholas a SMS, a whatsup and email requesting my refund, I have even tried to call him on his cell, he is ignoring me. I am not going to just leave this, it is a lot of money for me.</p>
