Fashion Nova review: Returned items worth over $300 and yet no store credit received

Hello! My name is Jenny Jimenez and me and my boyfriend Hayward Aubert ordered a bunch of items from this website fashionnova.com during their 19mil promotion. The following were the order numbers and the cost of each order/items returned:
1. 61874186 — $ 22.99 (+taxes) from hayward's order
2. 61994331 — $ 29.22 (+taxes) hayward's order
3. 61845313 — $247.28 ($193.92 from cc + $53.56 from GC)

The first 2 items were returned and arrived to their warehouse 1 wk ago 11/13/20 per USPS tracking. The last item was returned 11/16/20 per United Delivery Service (UDS) tracking. I did not even received the last order because of a mistake in the address and Fashion Nova wrote me an email since they do not have a phone customer service available to communicate with the shipper regarding returning the items to them which I did. The customer service at UDS was great at helping me return the order to Fashion Nova when I showed them the email. I have contacted Fashion Nova customer service multiple times and was given case #04014232 for the first 2 orders and case #04007507 for the last order which states that someone will contact us within 24 hours for them to respond. These case numbers were created both 1 week and 5 days ago respectively with no other follow-up reply which is not what they stated in the email.
We are still waiting for the store credit as we know in their stipulations that they do not issue a refund to the original form of payment which in this case, I think they should as it has taken way longer time than they have said/mentioned. It is definitely not an easy return process at all.
Until today, we are still waiting.
