Symphony Limited — poor quality and worst cooling pump

I have purchased a symphony touch 35 model on 27/04/2018 and on the first day the voice assist feature stopped working. I contacted the dealer and he said that he will send the symphony customer technician to repair it and he will not replace the cooler. Another day the service technician came and changed the pcb (Plastic circuit board) of it and the problem was fixed. I also thought that sometimes it happens with electronic products.
But on 03/05/2018 the cooling pump stopped working and i have again called the symphony service technician to fix that, but he came after 2 days and opened the pump and said that the pump is jammed, he opened and scratch the shaft by blade and oiled it and it started working.

Again after 10 days the pump again stopped working, now i am totally frustrated by this product, i paid 10, 000 for it believing on the brand but its quality is worst and local coolers are better than this.
Whole summer after every 10 days i have to call the technician and wait because the technician says that he will not change the pump until the pump is completely dead and he again opened, scratched and oiled the pump.
Now, i want that the company will replace the cooler with a new one. I don't know why i purchased such a small garbage for 10, 000. And i also want to know why the company is not replacing the defective pump and only oiling it.
Is this symphony they are only spending money on advertisement and not on product quality and service.
