I am based in UK. Useless company. Sonic Tooth cleaner. Item didn't work and company refuse to refund. Smartocity have debited more than $3500.00 to the card I used. Could not find an international phone number and CS said they cannot receive or make international calls!! I consider they act this way because so far away. I have instructed a lawyer but company refuse to give a registered address to serve legal documents. If anyone knows of correct address then please let me know. Thank you.
