Pathetic service

Internet has very slow speeds and when you try to contact them the queues are so long that no one ever answers, same with the online chat... Everything takes forever. We have decided to upgrade from the R250 package with hopes of improved service but with no success... On the website you select the upgrade option and then a pop-up message appears stating that the changes will take affect immediately but when you proceed you get an error message stating that you can't upgrade because a cancelation was requested but displays someone elses number.... Nothing ever works right!
