Do not keep to their promises , dont care about their customers

We have an internet cafe in Jules Street , Marlvern. We had a contract with Wirulink for interent services which had been running for the past five months . During November 2017 we could not get any internet coverage and contacted them. They took 5 days to attend to the call which every day within the five days they promised that their technician were on their way. which was a lie . We called like ten times a days and get the same response technician on their way. Eventually when they came we were told that they cant do any because the tree had grown and they cannot get signal. On the 29 November 2017 they took all their equipment and informed us that they will refund us within 3 day. which they did not do until today the 6 December 2017. I have spoken to a manager by the name of Shannon who promised payment by the 5 December 2017. We have lost business now for three weeks because of Wirulink and their empty promises . They also debited my son account ,which they need to refund us.
