I happen to really like Wharby Parker eyeglasses. I have a pair. My son has a few, and my daughter just ordered some. She needed them before leaving for a trip 3 weeks out and was assured that would not be an issue. After 2 weeks she began calling customer service and each call ended with assurances that her glasses would be delivered the next day. Finally, 2 days befor the trip I called and had a supervisor get involved. He assured me again that the glasses were ready to go out. He changed the delivery address to my home and said he would get back with tracking info. He never did. I called him. Again he promptly follow up one way or the other by the end of the day. Sadly and I suppose not surprisingly he did not.
Mistakes/issues occur. But it seems after day upon day getting assurances which were false all credibility was lost.
Please treat your customers with enough respect to tell them exactly what is going on. And give your customer service people some way to get real information they can pass along.
