Hisense terrible after sales service

I am absolutely disgusted by the service provided by Hisense and their service providers. We bought a washing machine and the belt has broken . I had to logged 5 calls over 3 weeks before a technician came out eventually after a month.It has now been 6 weeks and it has still not been remedied. I have called 8 times and sent numerous emails to different people . I keep being told they are waiting for the part and that they will call the technician and call me with a progress report , not even once did I get a call back . Now after having no washing machine for 3 months I am simply told " go back to the store where you got it and get a replacement " REALLY ?? Please can Hisense email me as I am now out of the country and provide me with a solution. 3 months to repair a belt.
