Motorola Solutions — motorola bad service centre

I bought my new motorola e4 plus. After 12 days while using it got switched off suddenly when i restarted it, the phone's touch got very slow. Then i visited to motorola gallery in ghatkopar west. They told me that the touch is not working, they will repair it and give back in 3-4 days. I had waited for 6 days but the didn't get repaired i again visited there they told me sorry sir the part are coming from somewhere please wait for 3-4 more days we will repair it and call you as soon as possible, again after 5 days they called me and saying that the parts are not yet arrived you will have to wait for again for a week. I am asking whether the parts are coming from dubai? What kind of service they are giving to us, i am very upset with the kind of service they are providing to us.. The worst service of motorola.
