Good content, horrible customer service

It's been almost 2 weeks now that I've been trying to speak with someone regarding a refund where I was overcharged 8 times the amount I opted for which was a R249 Black Friday special. I received an email that had the options and I opted for the premium option which was R249 for 12 months, as I clicked it not payment landing page was loaded or anything that notified me that the payment was made. Instead I received a bank charge notification of R1999 to Shaw academy??? So I've been trying to speak to someone for some time now and the only contact has been with a person called Glenna that keep sending the same email that they have been trying to contact me but have been unsuccessful all this time (that is to my mobile and work number) highly unlikely. I have received an email yesterday where we arranged to speak on my work number today today and surprise surprise, no one called. That only leaves to say that the customer service is to be nice, seriously lacking. Although the content is good, if you've been overcharged which there are a few cases on then it looks like you are swept under the rug with the rest of them. I don't do bad reviews ever but this is seriously ridiculous.
