Hongkong & Shanghai Banking Corporation [Hsbc] — transactions not able to convert into emi

Address:

Raigad, Maharashtra, 410218

Hi
I had been trying to contact hsbc from lat 3 months via call, emails and complaints for my transactions to get converted into emi's.
And now finally after 3 months of struggle i am successful in converting my transactions into emi's.

Now i would like to know whether going forth for all transactions do i need to go through all the pain and struggles i have went through to convert any transaction into emi or do i get any other alternative?

Pathetic service by hsbc credit card.
