Premiums Deductions/Submissions, No Cover Provided

In March my premium did not go through and for the month of March Budget sent me a text stating that since my premium was not received I was not covered. I then called to enquire about this, and they informed me that they will re-instate the policy for next month i.e. April, and the April Premium was successfully deducted on my account on 23 March. I later received another text on 31 March saying that they did not receive payment and my cover will be affected, which I did not understand because the amount for April went through already. I thought all these texts were sent in error. I then looked on my bank statement to discover that they have been submitting additional amounts on my account which had no funds. An amount of R264 was processed and rejected by the bank because I had no funds, and the charged per rejection is R130. On 11 April they processed the R264 with an additional R59, and they were both rejected with a charge of R130 each. On 15th April they processed the R264 again, and it was rejected for a charge of R130. The total that Budget owes for Bank Charges is (R130 x 4) = R520. Please pay my money ASAP, or else I am cancelling this policy with immediate effect.
