Angel Broking — Not at all responding correctly and not proper response

I bought 200 number of 3iinfotech company shares on July 2021 but now it it is showing 20 shares only. Regarding this I keep on calling to customer care, I dint get any response from them, kindly clear this issue. I made call to customer care five times they not even responding correctly. If you won't respond properly kindly provide me sufficient information regarding how to change my shares to other brokers so that I can change to them. Very worst experience
