Angel Broking — Double charge of DP for sale of shares

On 2/08/23 I sold two shares CERA and NIIT. The DP charged for the sale should have been 47.20 (@ 23.60 per share). Instead I was charged double, which is 94.40. I made many calls today to resolve the issue. 6 times the calls were dropped, and the ones that got answered didn't result in anything. Nobody could give me any explanation about the double charge. The amount may be small, but how you can trust the broker with bigger amounts then?
I got 2 emails that the problem was resolved, but it was not. Waiting for the resolution.
