Godrej Interio — requirement of shelves for slide n store almirah

I have purchased a slide n store almirah from godrej show room and the same was delivered on 17.01.20 and fixed on 18.01.20. On the same day i had asked the technician for additional two shelves. Subsequently i had booked for the same vide call no. N[protected] on 04-03-20. Technician called me and asked me to deposit the amount. When i asked for the details for sending money he gave his personal account details. While buying the almirah the dealer had quoted rs.680.00 but the technician is quoting rs. 1000.00 per piece. Again i contacted toll free number on 09.03.20 with all these details. They had told me that would come back with details but did not do. I this the type of service godrej interio provides? Kindly revert.
