I have send you three letters. But it takes 15 working days to reach your home, and then your family have to send it to you. That is why it takes so long, don’t think I am not sending any!

If someone wants to help me? thank you!

Thank you very much!

I am a little bit confused, because shouldn't be the last word sanmiyorsun?

I think it should be "sanma" (don't think)

So then it should be like this:

don't think I am not sending any:
hiçbirşey gönderdiğimi sanma

I think:
hiç bir şey gönderMEdiğimi sanma

yes I think so too. Thank you Ayla!
