bad m.

Bought a camera slider from Shenzhen Dslrk Technology Co., LTD. on alibaba.com. Placed order 28th of january,"because of the chinese new year holiday"my order was shipped on the 9th of february. Tought, ok, should be fine. Got tracking nr, was told it should be updated after 7-10 working days, there was nothing happening and I contacted seller why nothing is happening with the tracking he gave me another one-the first nr was not the tracking nr. Got the parcel on the 20th of february. Seemed to be fine, the dhl guy left. When I started to put it together I realised there are two wheels missing that hold the belt firm on the motor. I can not use the slider ever since.the seller gave me another tracking nr-he posted the missing part with china mail, tracking was showing movement till 27th of february, all the checkpoint in chinese. I tough it has left the country as after there was no activity, contacted royal mail UK with the tracking nr-they know nothing about the parcel and they asked me to get in touch with the seller and I am CURIOUSLY waiting..
