Awful customer communication; Billing is a mess

I downgraded my package to 20MB package for R400, and a Sales person contacted me and told me she can upgrade me to 40MB line for R499, However, my package reflects 20MB, and my invoicing is a mess. Please contact me to resolve this as I do not understand how I log tickets and then no one contacts me and they automatically get closed. I can not see any updates on the tickets that I log. This is unacceptable

I need someone to contact me
