An environmental services company hired EPC Group to set up SharePoint and establish a secure portal. The team was also tasked with fixing the client's SharePoint issues.
The client was disappointed with EPC Group's work. The team became unresponsive after receiving the payment and did not return the funds. EPC Group also failed to fix the client's SharePoint issues. The client primarily communicated with the team through emails and virtual meetings.
