THE WORST CUSTOMER SERVICE EXPERIENCE EVER!!!!!

In March 2015 i changed my banking details and i called Finrite Insurance, and spoke to Shimane to change the details on the system. He advised me to pay in that month's premium manually and my April premium will be debited from my new account. i paid the amount via EFT immediately and sent him proof of payment. At the end of April i noticed that the insurance hadn't debited and i called. in May and spoke to Florence who told me that my insurance had lapsed due to non-payment. i relayed my story to her and she told me to send the correspondence i sent to Shimane including the proof of payment. Yet again, i did that immediately and have had no response. fast forward to today 06.07.2015, i called and spoke to Thami, who asked me to hold and hung up on me. I called again, was again told you to hold and ive been holding for 30 minutes. The call center representatives are unskilled,have no concept of customer service and *********** to say the least!!!! If they cant reinstate my policy, then i want to be reimbursed for all the months that i have been paying because it isnt my fault that it lapsed in the first place. going on to 45 minutes and still holding!!!
