I worked as a Shopify Tier 1 Customer Support. I can offer you the my skills on responding to email and potential chat support tickets. It includes handling general inquiries and technical issues from different merchants. I was also managing complaints, refunds, and negative reviews. As a Tier 1 Customer Service Support, I am also assigned to do small basic CSS customizations like changing the color of a button, increasing the size of a text, etc.
I have also worked as a customer service representative where I handled an annuity / insurance company and my primary job there was to assist customers by answering inbound calls and delivering necessary emails for the customers.
