Complaint BROADBAND FIRST COMPANY

Good day I would like to lodge a complaint against broadband first as to the service delivery. I've got to get Wifi connection from them every month and EVERY time there is a problem with getting the connection.

I'm either told the problem is because high-line doesn't work or they'll tell you that from the house they plug someone unplugged the connection. After making numerous phone calls and WhatsApp messages to them and being assured it is connected only to find that after few hours again it disconnects, but still broadband first cannot get it right on their systems OR some of their office workers don't respond to all my queries and I have to call back every few days in order to be assisted!!

two weeks ago my daughter is atteding classes online, she missed about 6 lecturers i had to pay the internet cafe for her to attend also she had to write an exam the was no connection for the past two weeks and nothing is happening on their side in terms of helping cause I got proof of me sending them queries looking for help but nothing is happening.
