Tvidler ORBIO WORLD They added additional units to my order which I returned but was never credited for. Also, one ordered item was not delivered, nor credited. (There are already a couple of the same problem reported on RipOff) Kaunas
They added four units to my order (of two) which I noticed on checking the confirmation. I called immediately to report this, was told there would be no problem.
Then I was advised by email that it was too late to change the order but I could return the unwanted units. Turns out the return address is in Lithuania (although shipment came a from North American depot), registered mail, as required, costing about twice the items' value. I returned them by regular mail but was never credited.
Furthermore, one ordered and invoiced item was never delivered, nor credited, my reminders not even acknowledged.
