2. I face technical issue, does ATCKIT have any support, and how much does it chare?

ATCkit delivers certain free‑of‑charge services before or after sales, but in the sole discretion of ATCkit. Technical advice is available on a best effort basis within a few days response time. The Customer agrees to provide, upon ATCkit’s request, access to all information, documents and files necessary to perform the services. Additional service levels are available against a separate agreement and a surcharge.
