Items not delivered - no communication

I know Poetry stores only responds to compliments- but I wish I read all the online complaints before I made my purchase. On Monday 25th September I made an online purchase of 2 items - I chose expedited delivery which means I should get it within 1-3 days. I received 1 item and I get a mail to say my items will be split… no other info. I’ve sent 2 emails, written on their FB wall and a DM and I have still not gotten feedback on when my other item will be delivered. I only received 1 item. Communication is key - why can you guys not just pick up the phone and phone the customer, or even email with feedback. You must be doing really well that you can pick and choose to give good customer service. Why give customers the option to choose delivery option and not stick to it.
