I ordered * lip balms on **th August ****. My package arrived on ** but I was never contacted for delivery by Bluedart. So I went to Nyka app gave my alternative phone number as I was shown that my no was unreachable. I was told to wait for ** hours. I waited for two days again contacted Nyka and they told me to wait for ** hours. I waited for two more days and I was again told to wait for ** hours. Finally frustrated I cancel my order on ** of August. Nyka contacted me and told me that my money will be refunded within * days but its been already a week and no refund till now.
