Opti-cal Survey Equipment Ltd sold me a used total station which I later found out was not meant to be sold in the uk. they got this equipment from an auction somewhere in the uk and was not meant to sell it to me inside the uk. later, when i had problems with the equipment, i was refused speaking to the companies managing director. i have since found 3 other surveyors who have the same problem with the same company. what a sham. they have basically stonewalled me and refuse to deal with the issue or take the unit back and give me my money back. has anyone else had this problem?
