Tradeindia — inappropriate way of talking

Address:

Mumbai City, Maharashtra

Dear sir,
On 29/11/2019 your executive came, his name was mangesh shinde from mumbai (Andheri),
He was forcing to upgrade the package, we said him that will upgrade afterwards in few days.. But he talked very rudely and also insulted my dad by using inappropriate word, high tone, talked on value etc.. For this service had we paid??
Now i am confused should i upgrade with trade india or not?? What if again in future we get the same thing??

Words he used:- high tone, insulting words, aap logo ko dekhkar lagta hai ki app zyada upar wala package nahi loge, screaming yelling, rudeness, time kharab karte ho, told our manager ki aese logo ke site par itna mehnat kyu karta hai etc...
