Router not delivered .... appalling service delivery

This is the worst service I have ever received. I made an order for a Fibre line and I am expecting a router to be delivered and installed. I have been waiting for the last 2 weeks. I have called the call Centre EVERYDAY this week and all I hear is that someone will call me back. Not even one call back. I am soo frustrated and even when I want to speak to a manager they tell me no manager is available to speak to me. This service is sooo poor. They are easy to sign you up but when it comes to delivery they are very very poor. I am now trying to cancel my contract. I need Fibre for my work since we are in lockdown and working from home and this is really sad that the service is soo poor. I really expected more from this company
