Poor customer support from Linteg fibre

Terrible customer support ever, this is almost a week without fibre, they don't seem to care about their clients, how can their technician or whatever they call not be available to assist or not pick up their phones. I don't think I will continue to pay for a service I'm not happy with, can't be complaining with an issue that the service provider is failing to resolve over and over. I just need my refund and move on . There's a lot more options which never disappoint and value their clients.
