Non existent customer support

I purchased an LTE SIM card and received it on May 6th. I paid the 479rand fee for uncapped internet and also RICA it online at 1pm. The website states that the SIM would be activated 2 hours later after. It’s now 3 days later and still not activated. I have sent countless emails, messages via Facebook and Instagram and not one consultant has responded to me or even tried to fix the problem.
