People like that amaze me. I just honestly can't fathom their way of thinking. Did she hope to sell the item to someone else at a higher price? Is that it?
Clearly, she would've realized that you'd notice her activity on Poshmark and her 'I've been busy' excuse wouldn't fly. Does Poshmark have any penalties for sellers who don't ship within the allotted timeframe?
As a seller, I try to respond to messages as quickly as possible, and if the buyer decides to purchase, I usually ship the item the next day, sometimes even the same day if I have time to stop by the post office. Although I did have maybe two instances in the years that I've been selling stuff online (not just designer items) when I somehow forgot to reply to a message and ended up replying a few days later. I apologized and simply said that I forgot, without making up excuses. But those were just questions potential buyers had about the item, not them buying and then getting ignored.
She continues to tell me to "be patient." I have been patient for the past five days even without a reply. If Poshmark hadn't extended the shipping time by three days, I could've gotten my money back sooner. This morning I commented that I want a refund. Unfortunately Poshmark is fairly laxed when it comes to sellers like this. I no longer want the item as I feel quite disrespected. It would've been very easy for her to quickly say that she needs more time. I'm a pretty rational person but being blatantly ignored and told to "be patient" is a quick way to irritate a customer, especially when you're paying for expedited shipping. If she had sent it out several days ago, I probably would've had it by now. If she can't ship an item out then she shouldn't be selling in the first place.
