thredUP review: Unable to obtain any type of customer service.

On 05/21/2021 I ordered some items from thredUp. I chose the multiple payments option but was to be billed the entire amount. I tried for 1 hr. 15 mins. to request a change in the mode of payment. 7 times I was told that someone would be right with me to "Chat". I waited about 15 - 20 mins. for that "live person" to contact me via Chatbox at the website. 7 different times no one ever appeared. Finally the last time I entered the reason for which I needed assistance I began to enter "Cancel my order". Within 20 minutes someone was corresponding with me and I was able to cancel my order. There is absolutely no way to reach these people where you might accidentally speak with someone who has a pulse.
