Emaar Mgf Land — I am complaining about overcharged fine

This is to inform you that I had purchased a plot having Number 109-AP-227B-611.660 in September 2020.
For this, I have to pay some dues in installments. In January, I gave an application for name addition, and it took around 25 days by Emaar end.
After that, I need some other documents to clear bank loan formalities but am much delayed in getting the necessary documents due to the covid scenario.
There were around 45 days wasted in covid as your office remains either closed or worked with significantly less staff and got too much difficulty to sync with the bank and Emaar team. I have proof also while doing discussion with Emaar team which shows how thy delayed the things.
I mailed online also about my concern, but things are getting delayed again and again. Now my last payment of around INR 8, 45, 525 is due only, and I am not in favor of paying a fine for the delayed period due to Emaar end.
Kindly look into the matter and do the needful.
