I am a little worried if I did something rude to you.
I write this as I would like to know if we can do business again this month, and I understand that you are very busy, but I would be grateful if you could reply.
Thank you for your continued support.
I'm little worried that I might have done something impolite to you.
I'm contacting you because I'd like to know whether I can make a deal with you this month too. I'm sure that you are very busy,
but I'm looking forward to your message. Thank you as always.
