Neil Gill admits he likes "to have a yak".

But he was sure his penchant for a chat was not going to rack up large phone bills because he had found what has now proved to be a deal too good to be true.

The man from Wamuran in Queensland is one of a number of Kogan Mobile customers who have unexpectedly had their services discontinued.

Mr Gill signed up with Kogan to be a prepaid customer and pay $29 a month for unlimited calls.

He said he thought it was a good offer that would allow him to call his girlfriend, who lives an hour away, whenever he wanted and keep in touch with his father in Western Australia, who had been ill recently.

Unfortunately for Mr Gill, a pensioner, the offer only lasted about three months.

When he went to top up his credit a week ago, his phone kept getting an error message.

He called Kogan and was told he was not allowed to use his phone for business purposes.

Mr Gill said despite telling the person on the phone that he did not use the phone for business purposes, they would not believe him.

He said after much heated discussion, the conversation ended with some swearing and no resolution.

Mr Gill later received an email to inform him about the termination.

“We have further investigated your account and you will need to churn your services to a new provider as we believe you are not using the service for personal use and we are no longer able to provide you services,” the email said.

“Your service will not be terminated and you will have 90 days after expiry before your number goes into a passive status so you will need to churn out your number before this time.”

Mr Gill said Kogan must have decided he was using his phone too much, which did not make sense considering he was supposed to have unlimited calls.

He said he planned to take the matter to Consumer Affairs.

“It doesn't seem fair, unlimited should be unlimited,” he said.

Another Kogan user, Darren Chapman was disconnected in February after being with the provider for less than a month.

“What I would consider normal use, thinking I had 6GB to use. I didn't make many calls,” he said.

On February 5 he realised his phone had no service.

He tried contacting Kogan by phone and online but got nowhere, so Mr Chapman moved his number to Telstra.

“I couldn't have what I thought was an unreliable service. “

While Kogan may be losing business from customers it does not appear to want, it may also lose a number of other customers deterred by its actions.

Perth man Jay Shah signed up with Kogan about a week ago but since hearing about customers being cut off, is already considering moving to another carrier.
