No wifi connectivity even though I double paid.

I have have experienced the worst service and inconvenience so far with Webafrica and Vumatel from the 1st of this month as I struggled to be re-connected even though I double paid in error last month. From the 1st of the month I was told that they can see the double payment however they need to escalate to the finance and invoicing department and I will get an update in 24-48 hours and I heard nothing from them for a whole 5 days and that's when I decided to just pay for this month on the 5th of July and I was reconnected for the weekend but to my surprise on the 8th of July I was disconnected again and the system requires me to pay again?? This is truly an inconvenience to your customers. I would not recommend you to anyone!!
