iMark Infotec Pathetic service

We employed the services of iMark Infotec and have been at the receiving end of this bad customer service company. We own our source code for app developed and are yet to retrieve what we own. This company cannot be trusted, they have a huge turnaround of developers, create bugs in your platform so that they can get money out of you to resolve these issues. I have trying in vain to contact the director Piyush Gupta who does not even have the decency to respond to emails nor calls. I would NOT recommend this company for any app/web development.
