Unauthorized Debit & Incorrect Amount – 1Life Insurance

am extremely frustrated with the service I have received from 1Life Insurance. On 19 February, I called to request that my debit order be moved to April. I clearly stated that I would call back to confirm any changes and that no debit should go off before April. Despite this, my account was debited today without my authorization. I have now been told that debits are taken “in advance,” which does not make sense to me because I did not agree to any cover starting before April, and I should not be charged for something I did not approve. What makes this worse is that my usual debit is R760, but you debited R2798.99. My debit order mandate reflects an amount of R2781.26, yet you still took more than agreed. This is unacceptable and feels like a complete disregard for my instructions and financial situation. I want this corrected urgently, including a full refund of the amount debited or at least the difference above my normal premium. Please also ensure that my debit date is moved to April as requested. My name is Nompumelelo Hlomuka and my contact number is ***.
