Double deductions issues on retirement annuity

Good morning I'm writing to express my disappointment in how you've been handling my issue.

On may 5th i wrote an email to life@sanlam explaining that i just got an sms stating that my retirement annuity for April wasn't paid, i was perplexed given that i received an sms from my bank that the debit order went through.

When i checked my bank statement they had taken their money and the money was sent back again into my account without my knowledge.

When i called to find out they are telling me that they didn't get money because of insufficient funds which isn't the case because they took their money and when they did i still had sufficient money in my account.

If i had no money it was gonna bounce and charge me R8.50

I recently received an email from 3days back saying the issue has been resolved ans when i check they didn't resolve the issue they only spoke about my funeral plan which i didn't mention anything about.

Now i am being told they have to do double deductions which i don't understand because the issue is on your side, i had money you took and and brought it back which i don't understand why but now i have to pau double.

This is a huge inconvenience because I've neber had issues like this with sanlam, this was done for both my retirement and funeral cover.

How am i supposed to pay back double for issues you caused...
