bad customer service

I took a contract tablet from telom in january 2017 and opting for incurance never new what a prob this would be. In december the device broke and sent it away for repare. In january they contacted me for the first time since having the device. Never recieving a contract in the whole year. Upon quiry of this fact and requesting to speak to a manager no manager available. After a number of fone calls using lot of airtime found out that they sent terms and condition to a number that was not mine. Going back to the store where device was acuired only my real details was on the system. Only wanted a manager to speak to at finrite to atleast to give this isue atention. This leaves the qeustion where has true customer service gone.
