Bad customer experience and service

Vumatel started as the best service provider, but time goes by, they have started dropping the ball, this maybe due to the magnificent growth that they have experience which is introducing some arrogance. Our lines have been up and down in the last 2 weeks, this one has been the worst. We haven't wifi connection for the last 24 hours and these have not even tried to do the decent thing in advising what is exactly wrong in the area. Most of the people in my estate work from how and we have resorted in having to connect using mobile data. I understand that maintenance has to be done, but at least let your customers know of the planned disruption, this is the worst time to have problems with wifi. Vumatel needs to improve on their customer services and communication
