Money Making Scheme

Received a massage on the 25th that R408.63 will be deducted from my account on the 26th. On the deduction date only R110 was deducted from my account.No commucication or whatsoever which explains to me that i have to make another payment since they deducted partial amount which is the previous subscription amount.Received a massage today which says my services have been terminated cause my account is outstanding.On top of that i am charged R50 which these was not my fault cause my account was having money they just choose to deduct portion of the initial amount. Is this a money making scheme by robbing clients without informing them accordingly? If you can treat me like this how many south africans are treated the same and charged R50 which its not their fault?Its unfair how you make millions in marketshare while poor people are suffering because of your incompitence.
