Horrible after sales service

I purchased a smart watch in December for my niece as a Christmas gift, it arrived without its battery hence was not operational, I returned it to Snatcher via courier and have been struggling ever since to receive a replacement, I keep calling them have spoken with 3 consultants already and each promise to send a link to select a replacement but that hasn't happened either, I also send query emails to them which nobody responds to, I find this level of customer service absolutely pathetic and thus would not recommend their products to anybody.
