Hi. This is a pretty common problem among aspiring entrepreneurs. At first couple, it's incredibly difficult to gain customer loyalty and get them to trust you. Personally, this article and advice from the CEO of PissedConsumer.com, Michael Podolsky, helped me a lot with this recently.
Thanks to him, I learned that I have to be honest and responsive with my customers and now my business is thriving. I hope my answer helps you and your business!
