Angel Broking — To stop calls and message

I had recently opened a new demat account with a/c no. [protected] name Paritosh Kushwaha. After opening account i sm receiving so much spam calls for doing trading and they are torchering me to invest and talking so rudely first of all i how they got the number is an issue means angel brokinv is leaking there data thats so unprofessional and in a day i am receiving approx 20-30 calls. So frustated due to this unprofessional behaviour strict action should be taken against them will surely apply the compalint with higher authorities
