Croma — Incorrect Invoice printing and Rude customer support

Sir,

I had purchased an Laptop from croma online store, please refer the bill attached.

I just want to update the name in invoice from Venkatesh Suvarna to my company name c/o Venkatesh Suvarna
As this is the requirement of my office, but croma customer service and store manager denies to do so and spoke very rudely.
Change of the complete name is not valid/legal, but this is updation of name.
Existing name will still be part of the new name.

Will i get any solution on this or croma will loose a customer. I have been customer for more than 10 years and always chose croma over other online shopping.

Regards,
Venkatesh S
