Worst Servvice Ever

My internet got cut and after spending close to an hour on the phone with them i get told it was done by Vumatel which there is no way of contacting them. I still do not understand how it takes so long to reconnect it. When i asked if i will be refunded for my days of no service there is no solid answer. Their Call center is the worst i have ever experienced, you will wait for 30 mins on the line and you get cut off and re-join the que. If you know you only have a limited number of people working why is your number not Toll Free ? Why should i spending so much money on airtime to ask you to fix your mistake ? I am currently with no service of something i paid for.
