worst experience ever

they stopped debiting my account November I therefore started doing manual eft payment on the 20th as my due date is the 25th they then decided to load another debit order June without contacting me and I had already paid for that month was advised refund takes 14days or i can do reversal with my bank they then started charging me 202 stating its a debit reversal feel and around October they debited me again and i had to reverse it now they say I owe them 404 extra while my premium agreed to is up to date and they suspended my account.. non of the agents have been able to help and I'm told I must pay for that fee...
