All the problems we encountered with OpenCart because of customizations, problems of different nature, the only ones able to solve them where those from OC-Extensions Team
I had used OC-Extensions in the past, with our site amlcandles.co.uk, and have had no reason to contact support as they worked for me right out the box. With the latest extension I am using, After Purchase Review Invitation, I contacted the guys to ask about an change I would like to see. Almost immediately they got back to me and after a few emails back and forth. How happy am I? Very!
What an awesome extension! Great support from the guys. Store on Facebook in minutes. Fully functioning after the guys took care of some of my mistakes. 5 Stars across the board! Well done!!!
