Bangalore Water Supply & Sewerage Board [Bwssb] — R R number not received - BWSSB People rude behaviour and Not responding

My name is Antony Raj resident of Vishwa Priya Layout, Begur Road. II have applied for a Cauvery water connection and also paid the amount Rs.19750 on 04-Oct-2019 under the Demand Draft. Number 996880 dated on 07-Oct-2019. I have received the receipt also the receipt number is 27015 (attached for your reference).

More than 18 Months over but till now I did not receive R. R number, I keep on asking your representative (Mr.Mahesh) who is handling all the Cauvery new connection applications in our area. I did not get a proper response. Meanwhile, your department people disconnected my house water connection two times, bit the time your people behave in-appropriate way. I already sent a mail regarding this on 9th January 2021, but there is no action till now. I have attached the old mail for your reference. Again Today 23-Aug-2021 your department people came and they behaved rash manner and used inappropriate words.
As a citizen why I have to suffer a lot due to this. Is there any mistake from many ends? Your people have given so much mental torture. I have tolerated it till now. Due to your people, I was mentally affected and they hurt me a lot. I asked many times to please take proper action against this. I hope this time, I will get a positive response from your end.

Could you please tell me when I can get the RR Number?
