Taking to a Bot

I have had new fiber installation done last week I have tried to log nunneries faults with a WhatsApp service that takes ages to connect to a consultant,no phone number to call for support to explain the problem ,what is the point of having fiber of the are it covers is only where the router is,I can only pick up signal in my lounge where router is,best you send a technician out or come collect your router in the road in one thousand pieces,I will not pay for the first month as I have not used the inadequat service
