Very Bad Experience!!

I placed an order and paid on the 22 of May, delivery date 29 of May. On the 02 of June received email from Exclusive books, sorry for delay, because of the lockdown. 07J of une I send a email requisting feedback, next day received via email a ticket number, one of their agents will contact me. Did not happen.... 14 of June I send a email complaining about their bad service... On the 15 of June I phoned in, spoke to a lady, which name I have, on their system show goods received but not despatched. She promised she will look into this problem, and will contact me Wednesday 17 of June. I waited until end of business day, I am so disappointed in her and Exclusive books. I am a firts time buyer with this very bad experience!!!! What is to do with my order or the money I paid?!
