Tourtravelworld.com — Product and Services issue

I am feeling cheated by the company "TourTravel world .com" and its (parent company Weblink) in the name of providing the services of advertisement for my business. I took the services from them on 2nd December 2022 (Invoice No. WEB/REG 10766). They assured me that they will start my services within 7-10 days. However, it didn't happen in a month. They are providing an unsecured portal without SSL certification. I made the half payment and the rest of the amount is pending. I want the resolution of my issue, either they refund my amount or provide me the complete product as it is required for a business.
