Company Name to long for Checkout?

Actually I am trying to purchase the New Vostro 15 3590 model with 10th Gen Intel i5. But the problem I am facing is very unique as I am unable to type the complete name of my company in the space available on the "Checkout" page to avail GST credit. It seems the space available for only 30 characters/alphabets to be filled. So, at this situation I am feeling very helpless and I have tried many times to reach Dell sales team via helpline No. available on the website but unable to reach them. 

I would be grateful if someone can help me out.

Thanks
