What can Hello Peter Do to businesses who do not respond to customers cries

More of a question than a complaint, just submitted my claim for the device i lost and looking at the comment, complaint, grievances of the peple who have dealt with admin plus (Telkom's underwriter), i have a strong feeling ill be writing a review complaining about not getting a response nor phone. My question is, what does Hello peter do in a situation where the business has not responded to peoples cries, what can hello peter do as this is the last option people have to get their voice out there and be heard, I mean I have dealt with Hello peter for a long time and none of the problems I have had in the past years I have lost, I just want to know in an event where the business does not respond and the customer is still not happy. what else can be done to help resolve things
