I could give them a negative rating if I could, I started using Mweb about a month ago and the first debit order went through yesterday. I was charged for September already in this month which would’ve been fine if they had been clear with me from the start. I specifically asked if they charge for their services in advance before I gave them the go ahead to come install the fibre and they stated that no they charge after the services have been used at the end of the month. I had to call them only for them to explain to me that I got charged the amount that was charged because they charge in advance which got me even more upset because they wasted my time as well.
