Interswift Moving & Storage Pte Ltd

I have contracted Interswift moving and storage Singapore to ship all my items of 93 boxes to Netherlands from Singapore.
After I paid they have very bad service. They did not tell me when my goods are shipped and no communitation. My items are ship from Singapore to U.K. Which is unknown to me. As in my contract its from Singapore direct to Rotterdam. Now it's port is in U.K and they put in their agent wareshouse wich is Simpsons Removals & Storage Ltd Blue Hawk House, A1 Manor Way Business Park, Manor Way, Swanscombe, Kent, DA10 0PP. They leave all my items in their storage for more than 6 months before delivering it to me.
They have the worst service as they did not count any of the boxes delivered to me. I have 6 boxes missing and they claims that everything have been delivered but have no proof of any delivering documents.
I contacted Interswift Singapore regards to this matter and they did not investigate right and even put words in my mouth. They told the insurance company that I claim that I have receievd all 93 boxes but claimed that 6 boxes were missing.Arvin G. Mansukhani the Business Development Manager make the claims for me. I have all the emails and delivery documents to proof that I did not say I receieved all the 93 boxes.
