Notice to stop activities

I own a shop which is a part of Local shopping centre. The shop is one of two shops situated at the back side(ground floor) of a residential building. The shop is commercial and has been used for commercial purposes (in accordance with MDP) since the past 50 years or so. Now I received a notice stating the following:- “Whereas, it has been brought to my notice that Property/ Portion of plot No. Property No. XX, Shopping Complex, XX AREA, Delhi is being used for the purpose other than Residential by running Trade/Factory/ Industrial Activities Car Repair with compressor in violation of the existing policy of the MCD and also against the provision of the MPD-2021, which amounts to misuse of the premises“ Now I have 2 questions here:- 1- If they have sent the notice assuming it to be a residential portion that is being used as commercial 2- Or if they counted the auto workshop as “Industrial” because as per MDP-21 auto workshops can be opened in LSC 3- Or is it because of both the reasons.
