inception date debacle

I've had an active policy with Santam for my vehicle and wedding ring for over a year. I called in mid April to get a home content quote. Lesego gave me the quote. I was happy and accepted the quote to be added onto my current policy (vehicle and wedding ring) I kindly asked the home content policy could be incepted for the 1st of May 2015. Lesego said that he would arrange with his accounts department to do the debit. I received my electronic schedule, only to find that it was incepted for the 1St of June 2015, i emailed to get the date rectified. On the 4th of May I realised that my santam debit had not been deducted from my account.I called in to query this, only to be told that they will just double debit at the end of June. How could this just be done without informing your client? I then get told that santam takes full responsibility for the mistake, which i appreciate. BUT, when i wanted to confirm that I do in fact have cover for the month of May, I am told that no one can confirm this? BUT I will still be double debited at the end of this month? I find this treatment disgusting and feel sick to my stomach even thinking about your claims process/Other policy queries.
