Rain is ****ming it's clients by Deducting R1093 for a (R595) monthly subscription

Rain deducted R1094 this month for a R595 monthly subscription. Which is quite alarming to say because I just got this router last month. We payed R499 for the router and another R250 was charged on the 15th of January, the only time I get my monthly income which I was told I wouldn't be charge 595 for the first month. You made it so convincing that I won't have any problems. Yet here we are again being financially **** to pay for the inaccurate invoice. This is like the time even though I cancelled you guys shutdown my Rain 4G sim card two weeks after I payed for the first month and demand I pay another for the next to officially close the subscription that already got shutdown. This is *********, unprofessional and greedy if you think you can get away with this. I better get a refund or a thorough explanation what made you think charging R1093 would go unnoticed
