Hindustan Petroleum Corporation [HPCL] — transfer of gas agency without notification

Dear sir/madam,
I have a hp domestic gas connection from the year 2000 itself, initially i have been allot to kumaran gas agency, k. Pudur, madurai at about 5 kms from my residence and location. After some years, all of sudden it has been shifted to another gas agency named sri gomathi gas agency which was about 10 kms away from my location and residence, thereafter i have faced lot and lot of troubles with them due to improper response and delivery not in time and when asked threatened by the gas agency owner, that being member of council of ongc, hence nothing could be done against them, at that time govt. Of india, introduced portability of gas connection, by then i again transfer to my first agency kumaran gas agency and till now it has been going smoothly without any trouble. Now this time when i booked for cylinder on 06.04.2020, once again i have been informed that my connection was transferred to one solaimalai gas agency again located at about 10 kms away from my residence and location.
When i inquired it with kumaran gas agency, they replied that, it has been done by the hpcl itself.
Now again i have been in trouble, being in lock down crisis, i tried to the numbers given to me for contact further, but ended up in vain, every time i called the number it is in out of service area, already one week gone with the booking, being distressed,
I request you to kindly look after the issue and do me the needful.
