Non exciting customer service

Non exciting customer service. When I first got car insurance they were cheap and helpful. Over the last year their premium shot up to almost double so I canceled, with my new insurer on a threeway call on the 22 of March. Informing Standard bank my debit order going off on 25 March should be the last, thus giving them a full months notice. And from 25 April my debit order with the new insurer will commence. Come 25 April Standard bank still debit my account. After numerous calls and mail they only cancel my insurance on 4 May because of having useless employees this was never done. From 25 April to date I've been trying to get the last debit order refunded. Witch they said they would do but since had one excuse after the other for it not happening. And for the last 2 weeks they point blank refuse to reply to my mails. Even the customer complaint tickets are closed without contacting me, just letting me know the issue was resolved. At this point I'm considering opening a case of theft at the police station. If this is how they conduct a case of returning a wrongful deducted debit order, i feel sorry for people actually submitting a claim.
