SHOCKING AFTER SALES SERVICE

really poor after sales service, first ultra sound machine lasted less than a month, box was delivered unsealed with an empty compartment im assuming where the gel would go that its supposed to be supp**** with, unit was collected and replaced once again unsealed box, once again empty compartment and this one lasted less than 3 months. device used maybe once a day not even every day, max 15 minutes. they wont collect second unit and refund - cant keep replacing and it lasts a few weeks, they say probably power surge but none of our other equipment has failed - their product should not be sold in sa then! i demand a refund and collect faulty machine ULTRASONIC PHYSIOTHERAPY INSTRUMENT
