BAD SERVICE

I received an email in August to say that metro fibre has taken over. Last week Thursday i lost network coverage i called i was told someone will call back no luck Called back friday was told they cant do anything till Monday. Monday morning i called was told they need to call metrofibre and will get back to me no one called. I called back Tuesday was told someone will call no luck after sending a bad service emaik i received a call to say apparently a technician was out on friday and there was no one at home, yet i work from home so was told they will be out later that day or next day being Wednesday,which i called and sent more emails that keeps getting closed saying query resolved but wasnt. Today i called metro fibre and was told they cant assist me. My kids are busy with exams and i need the fibre and i keep telling them. I pay 900 a month and this week due to bad service i had to buy 900 worth after data for my kids to complete school and exams for the day
