Nilkamal — Mayor Midback chair purchaser GST No not included

Order no.1395, when i placed order there is no provision visible for entering customer GST no. The very next day of order confirmation i contacted the customer care and informed about GST no details, in addition to that mail also sent. When i received the material customer GST no was not included. I have complained it to the customer thrice and repeated mails sent there was no response. Finally customer care executive informed me that the invoice can't be modified.
Useless lethargic customer care peoples, good for nothing. Better not to buy anything online from Nilkamal. Some how they manage to lineup good product models, they don't bother about retail customers.
