Easy to find fast and proficient chat support
My issue is resolved in under 5 minutes.. I was able to speak with a live confidence human being in under 30 seconds.. I was charged for subscription that I forgot I had subscribed to and I no longer needed and the chat agent Kara had my problem resolved in no time. Locating this chat support option was easy and not hidden amongst FAQs or literature used to distract and deter you from reaching out
