Useless 1 star after sales service and support.

I wish i had read the reviews on this site before purchasing from TEVO. Zero after sales service or support.No response to my emails,bad attitude from their staff when you finally get through to them which begs the question-why are they in business in the first place? 75% of reviews are 1 star-let me justly add to that figure.Stay away from them and their substandard products.
