Terrible customer service - waste of time

Shocking service from Netstar - it’s been two weeks and they have sorted out a tag issue with their unit. They use unprofessional “fitment centre” that book appointments , don’t pitch and neither even call you to advise they aren’t coming. Escalations department says they will sort it out and still nothing. How can you expect me to pay for something that isn’t working?? Neither are your teams competent enough to come out and fix your unit???
