I have purchased 4 strip of androanagen medicine online on 7th may 2019 from 1mg and paid rs.797.16 in advance but received only one strip in previous week.

When i checked the package received it was carrying only 1 strip of medicine, so i made a complaint on 1mg portal on 12.05.19 and yesterday i received a mail from 1mg mentioning that there vendor has confirmed that he have dispatched 4 strip of medicine.

But the fact is i have not received 4 strips which i have ordered. Now what should i do so that i get my complete order or refund.
