Service is poor

I have not had my services working from Wednesday ,I’ve sent emails after emails but no one makes contact it’s just an automated response on email and on their chat they keep saying their checking my coverage which 4g. I’ve not been able to work,nor do my assignments and my kids can’t watch tv or their social media because it’s not working ,it says 0 mbps. It’s also school holidays how will myself the kids managed as we are home for the week holidays. They lack efficiency and customer care service .Ive never been frustrated like this.
