This was my first/last time trying Zenni. Frames are cheap, but one of the prescriptions (ordered two same script diff frames everyday glasses) is off - super blurry. Been trying to get a refund for 3 days because they obviously got the script wrong. Their CS is very slow - wonder if they're trying to drag out process to the 14 day mark to avoid refund. Extremely annoying. Have been ordering glasses online for 10+ years, never had this much difficulty.
