Pathetic service from Sinotec after sales service

We bought a 10kg sinotec washing machine less than a year ago. We started noticing that there were spots on our clothes so being in the 1 year warranty we contacted Sinotec on the 10th of January 2019 after numerous attempts to arrange the pick up (6 - 7) we were informed that the machine was not picked up yet because we moved (my wife confirmed that we would be moving on the 25th of January) I took over the complaint on the 4th of february after yet another failed pick up of the washing machine i then arranged for the pick up on wednesday the sixth of february 2019 which was finally completed. When we followed up today, there was firstly no indication that the machine was even with them. They phoned my wife twice today to try and arrange the pick up after I phoned today to speak to someone senior a lady called Christine phoned me to say that the machine is still with their COURIERS and has not even been delivered to their offices yet!?! I dare anyone from Sinotec to try and convince me that this is the type of service and fair treatment that they would want to give to their customers and I for one will never buy another product from them as well as actively discourage anyone from supporting this pathetic excuse of a company
