Bad customer service - ***********

i bought a washing machine on Saturday 30th September at Ottery Hypermarket. The person at the applinaces, Terence was not helpful at all and spent all his time on his cellphone rather than assisting me. The machine i wanted was sold out and i then took the ''display'' machine and got a R100 discount. We then proceeded to pay for the machine which took another 20mins to do as we needed a manager to sign off the discount. Finally, i leave the store- i get home and there are parts missing which should have been checked by Terence. I the proceed back to the store and this time Terence is on his cellphone again and not interested in what i am saying. He then takes the missing parts from some other washing machine and hands it to me and just walks off. I then request to speak to the appliance dept manager to complain but he takes Terences part and say he is ''going'' through some stuff. I tell him that i would appreciate if he could send a technician to me to check if all the parts are right and if the machine is working. I give my details to Nathaniel who tells me they will send a technician on Monday, 02/10. This morning, Terence calls me and all he asked was ''is your machine working''? ''did you test it''. I tell him im not sure as i did not use it as yet. He then just says ''good-bye'' and ends the call. this is the worst customer service i have expereinced, you guys are pathetic to say the least.
