Very Angry and Disappointed RAIN Client

I have been with RAIN for a while now and sadly for more than 2 days now, I have had absolutely terrible service. Prior to then, everything was perfect, for just over a year. I am currently on the package for speeds over 100MPS and a lady told me that my package is for 30MBPS. She then transferred me to someone who tried to upsell me to 100MPS, after I have already paid for 100MPS. This is the third day with my speeds still at 30MPS and now when I call rain again, they confirm that their escalation team will contact me before 17h00, which is ridiculous. As I have warned the consultant I was speaking to, should this not be resolved before 10h30, I will be escalating this with the ICASA as well as the financial services board of South Africa. RAIN's service has been amazing since now but I don't understand why an internal error is having to affect me as a client so Drastically.
