Worst customer support

I am extremely disappointed with Webafrica's customer support. I started my fibre package a month ago and was given a 3-month promotional rate, which was clearly stated in my email confirmation as R499 per month. However, every time I reach out for clarification, the agent Emily K insists that my promotion has ended, and I need to pay the full package rate. To make matters worse, the Webafrica portal is showing a different amount—R549 instead of the R499 I was told. I simply wanted an explanation for the R49 difference, but the responses I've received have been confusing and unhelpful. It's frustrating dealing with customer service that seems incapable of addressing straightforward questions. At this rate, I'm seriously reconsidering my choice with Webafrica.
