Dell India — Delaying in order product and not accepting company mistake and charging 15% deduction in case of cancellation.

Dear Sir/Madam,
I ordered the Dell Inspiron 5510 model on 31st Jan and on the Dell website It was showing that It is eligible for Fast delivery and delivery date was as of Today(03/02/22).
But I have checked and found that there is no change in status so I have called them and asked about product status. They said It is in Technical issue and while filling the form in place of Company name you have not entered your name.(I have asked them Sir I am not running any company and in place o[censored]sername I have entered my name and in place of company name I have entered NA(not applicable) even if that is the thing then It should be company responsibility to highlight or give some hint for that field value).

Now They are saying If I am cancelling my order then They will deduct 15% money and also I will get money after 15 days.
In case if I am taking this product then It will take one(1) week of time.
