US telecommunications giant Verizon has issued Netflix with a “cease and desist” letter.

The letter came after the streaming video service reportedly told consumers Verizon was behind slow connections.

“There is no basis for Netflix to assert that issues with respect to playback… are attributable solely to the Verizon network,” Verizon wrote.

Netflix responded that the firm was trying to “provide more transparency” to consumers.

“This is about consumers not getting what they paid for from their broadband provider,” said Netflix.

In March, Netflix chief executive Reed Hastings hit out against internet service providers such as Verizon for demanding a fee to maintain video quality.

Nonetheless, in April, Neflix agreed to pay Verizon to establish a direct connection to its network to ensure content was delivered to users’ homes.
