****py service from a big company

I ordered earrings and a pair of Jeans from Superbalist two weeks ago. I received the jeans but the warehouse staff had packed the incorrect earrings. I informed them about this and they asked me to log a return and follow the procedure. Till today I am still waiting for earrings that I did not pack incorrectly but someone else did. I feel like they need to improve their customer service and speed up the process of a return if it is their fault bcoz surely they have to acknowledge their wrong in some way. I honestly feel like they should give me the earrings and refund me for the inconvenience of waiting while they go on with business. I feel that it’s such a ****py service for such a big company. They are acting like a spa a shop. Yes, if I was wrong, I would not mind waiting but this is ridiculous
