Unfair Business Practice

When I initially joined Corlink, they were friendly and helpful and I was happy with the service. I then moved to a different house where I didn't know they had no coverage. Since their payments are in advance they deducted the payment for a month where they rendered no service to me, when they had to refud me, they argued that I had not given them 30 days cancellation notice, as if I cancelled out of my own will. They also cited I was supposed to advise them before moving etc. As a result I had to pay 2 service providers for the same thing. This is unfair, taking advantage and capitalising on a technicality that is not applicable and never communicated and that I never signed for. The excuse about me not telling them about my move is a policy only app**** to me clearly because when I spoke to Zama, she promised to speak to Finance. I had to be the one following up when a week passed without feedback. I will never recommend or use Corlink again.
