Chicme Sent me items that were the wrong size and wont take return El monte California

All the items i bought were way too big for the size smalls i ordered. Ive been trying for weeks to get a return address. I emailed and sent sku numbers and stopped getting any type of response regarding my return, that is required within 30 days. Seems like a scam. The sizes were like maternity sizes. Im typically a size medium, but i bought smalls and they were way too big from the merchant No one i know wants them nor can fit them. All i ask for is a return address and i get nothing. I need help from what seems to be a scam. Is a return address to return the items for a refund, within the 30 day policy, asking for too much?
