Indus Towers — Non Payment of Rent Increase as per the Agreement Tower ID 10790008

The Tower ID 10790008 was installed on my land during 2008 in the name of Hari Singh who expired during Aug 2019. as per old agreement a clause for the rent increase of 10% every 5 years was incorporated. As per that the last increase was given in Aug 2018. The agreement was transferred to my name ( Darya Singh Sangwan ) after death of Hari Singh on 01 Aug 2021 and the rent increase clause was modified and agreed by both the parties and the modified clause incorporated read as " The rent will be increased by 10% after every three years starting from the last increase."
I had tried at all the levels but no satisfactory reply has been received so far.
A copy of Page 3 of 11 with rent increase clause is attached for ready reference. As per this the rent was required to be increased by 10 % from Aug 2021.
I would request you resolve this issue at the earliest please.
