We are migrating our website from nopCommerce to Magento. The package we purchased is closed to $600. Cart2Cart asked for our live Magento install credentials and then simply mentioned "we'll get started soon". Despite my request of when they would be getting started they simpy responded with "as soon as possible". A couple of days in I attempt to access my Magento instance for development and it will not load - looks like they got started. Luckily my "live" magento wasn't live yet.
Their customer service is nonexistent. Per three request I make for status updates I get a response saying "our team is working on this and will provide you with the test import data when it is ready" when I asked for a timeframe (not an exact time mind you) they respond with "Sorry, we cannot provide an estimated time frame." However, they don't mind marking the job as urgent for you if you wish.
For the record, I have not sent an exhausting amount of update request to the project rep for Cart2Cart - so they have no reason to not respond. The only way I have been able to get someone to respond timely is by getting a chat representative on the case - who then connects me to someone who can't tell me anything.
I look forward to telling my CTO that I gave $600 dollars away to a company who won't provide an update and all that they've managed to do is migrate products (a small part of the project) with incorrect inventory.
