I canceled but they ignored it and still continued

Good day<br> <br> I selected a internet package by Web Africa for a 4mb ADSL line with Data. I had some troubles viewing my ticket (#***) and responding to a billing ticket. a New ticket was made (#***) and someone responded but I got poor service. The person said i can now view the original (the first ticket) ticket but i was still not able to. So i got impatient and asked how far is the progress. I got no reply and told the person that i was canceling the order. Now i see that I'm about to be billed for a service/package that i canceled.<br> <br> i have taken screenshots of the whole ticket just in case the ISP decides to remove the ticket.<br> <br> Please assist.
