RAIN data is just up to no Good!!!

14 days ago I signed up for Rain 4G 24/7 unlimited data. Rain immediately debited R475 from my account. Upon receiving my Sim, I realised they sent wrong 19 hours limited data. I immediately cancelled Sim. Rain apologized for their error, cancelled my Sim and assured me of my refund within 7days. It's gone to 14 days already and they haven't refunded me R475 as yet. Just giving me the run around! You can't phone them because they believe in sound borne spreading of Civid-19. Every time a different support technician will make a promise of refunding you but they haven't refunded me. I've received emails from Zininzi, Tsholofelo Mosili, Keanen vN, Thembeka Bheli & now on my 14th day to Sisipho Ngcanga but where's my refund of R475???
