Terrible customer service!

I have been struggling since the Friday 13th of May with my internet payment. My payment should be R529 but they keep wanting to deduct R799, I have been in contact with the WEBAFRICA representatives everyday since, everyone of them keep telling me to wait 24-48 hours, 24-48 hours later I am still waiting my internet is still offline. Today the 18th of May, I contacted them again and yet again the representative said they are escalating the matter to the financial department again and want me to wait another 24-48 hours. It's now been 5 days since my internet been suspended due to payment issues that's caused on their side. I don't recommend them to anybody and I don't know why I am still here!
