Clientele - what a dissapointment

My agreement with clientele was that they would debit my acc on the 22nd of every month. In 1st week of July i deposited money in my acc & they debited a 2nd premium, i didn't undestand why as they had already debited 4 dat month. I sent them an email wth my details excluding my policy no which i did not have @ the time & they responded by saying they need the policy no in order to assist me. The same month i got an sms saying i have not paid my premium. An agent called me regarding non payment and i told her i had proof of payment. The sms's kept coming every month after my premium was debited and again i called their call centre which takes 5 minutes before you can speak to an agent. This coused a mess wth my debits & i ended up skiping 1 month payment which they had said it was two payment (once again wrong) an agent called me & i again told her i had proof of payment and made arrangements to pay 4 my 1 month unpaid premium. This months again they double debited me. I decided to reverse both payments and as usual they were quick to send an unpaid sms. I called them and asked that they cancel my policy and re-emburse all my premiums. The agent advised that they will repay me.
