No service from Vivekan despite payment.

Secmac Containers purportedly contracted Vivekan Logistics to deliver two containers. Despite apparently having been paid by Secmac, Vivecan logistics demanded additional payment, supposedly for insurance, and we would be paid back 98% of this amount once the containers were delivered. Despite Vivekan not doing the delivery because Secmac failed to provide, and despite numerous efforts no refund has been forthcoming from Vivekan. No acknowledgement, no answering of any e-mails. No phone contact numbers.
