(Adds Level 3 response, updates CenturyLink shares)
June 16 (Reuters) - A CenturyLink Inc employee claimed she lost her job for blowing the whistle on the telecom company's sales culture, according to a Bloomberg report on Friday.
CenturyLink's shares were about 4 percent at $25.89 in late-afternoon trading, after falling as much as 8.1 percent in the session.
The employee claimed she lost her job after notifying Chief Executive Officer Glen Post about the company's sales practices, that charged customers for accounts they had not requested. (https://bloom.bg/2syoQgq)
Shares of Level 3 Communications Inc, to be bought by CenturyLink for about $24 billion, also fell by about 4 percent.
The complaint alleges CenturyLink "allowed persons who had a personal incentive to add services or lines to customer accounts to falsely indicate on the CenturyLink system the approval by a customer of new lines or services", according to the report which cited a lawsuit filed in Arizona state superior court.
CenturyLink did not immediately respond to a request for comment, while a spokeswoman for Level 3 declined to comment. (Reporting by Narottam Medhora in Bengaluru; Editing by Shounak Dasgupta)
