A VIDEO showing a grandmother being subjected to a foul-mouthed torrent of abuse from an employee of a Newport pizza takeaway has gone viral.

But the business's owner has claimed the video, which was posted on Facebook late on Friday, does not show the full story.

The video was posted by Coleg Gwent student James Aldridge who said he had posted a one-star review of the Square Pizza Co in Cardiff Road on Facebook after food he and his family had ordered did not arrive for almost two hours.

The 16-year-old said not long after he had written the review he had been called by an employee of the takeaway who subjected first him and then his grandmother, Elizabeth Gallear, to a torrent of abuse.

When the video, which has been shared more than 200 times, begins the call has already started, with the phone on speaker and clearly displaying the number of the takeaway.

The voice on the other end of the line can be heard calling Mrs Gallear a ******* ugly *****" to which she replies “You’re absolutely disgusting for a pizza shop.”

Mrs Gallear replies: "Phone back when you learn to talk tidy" and tells the man to “go and shove your head in the pizza oven” before he makes an anti-Welsh slight against her.

James said he had originally rung to order the food at 7.15pm on January 6, but it did not turn up until about 9.10pm, by which point it was going cold.

He said after he answered the phone and was subjected to abuse from the employee he had passed the phone to his grandmother and begun to video the interaction.

"I'm only 16 but I wasn't having that abuse," he said.

James' mum Tracey, aged 43, said the call was "disgusting".

But, in a post on his own Facebook page, the business's owner, Zaman Ahmed, who said the voice on the video was not him, said his staff had themselves been subject to a torrent of abuse in connection with the order before the video was filmed.

"I will always stand by my staff if they are in the right, and I haven't opened this business to accept the type of abuse and disrespect that was given to us yesterday," he said.

"However, I also don't condone or agree with that member of staff calling the customer back and also acting in the way he did with the elderly lady.

"It makes him no better than the customer.

"Therefore I have taken the decision to terminate the employment of that member of staff."

He added he had suspended the firm's Facebook page as he was receiving abuse from people who had seen the video.
