No delivery, poor service

I moved into a new house this weekend,I gave mweb notice when to cancel at my old house and when to install in my new house,which was meant to happen today at 7.30am by Vumatel and mweb never cancelled my old fibre line and Vumatel never showed up to do the new install at my new house,this is shocking service and if the is not sorted out tomorrow,I join another internet service provider
