An 84-year-old shopper was allegedly called ‘a stupid b****’ by a supermarket worker after he crashed a line of supermarket trolleys into her car.

Mary Cunningham was left “shocked and traumatised” following the incident at Morrisons in Watford.

Ms Cunningham, of Croxley Green, was leaving the car park in her Nissan Note when her family says a row of 20 trolleys hit her car, and the staff member shouted: “You stupid b****. I’m going to be in trouble now!”

The collision happened on May 30 but Ms Cunningham and her family were left “dismayed” by Morrisons’ response and says the company have still not paid for the damage to her car.

They say after the crash, Ms Cunningham went into the store, supported by onlookers, and was  given assurances by staff the situation would be resolved quickly.

Ms Cunningham’s daughter Susanne said: “I have been shocked and dismayed by Morrisons’ complete disdain for my mother.

“Their member of staff caused substantial damage to her car – which will take £1,500 to repair - and yet they have left her high and dry.

“Morrisons is a multi-million pound business and they have a slick PR machine that says they support local communities and the elderly – and yet when they damage an old woman’s car and abuse her in broad daylight they don’t pay a single penny to put matters right.”

She added: “This whole incident has been deeply distressing and upsetting. I will never be able to forgive Morrisons for what they have done to my mum.”

On August 30, after the family complained through social media about their experience , Ms Cunningham received a letter from Morrisons apologising for what happened.

It was accompanied by a £20 voucher and flowers and chocolates will be delivered to her home as a “gesture of good will”. However, the family remain angry and frustrated.

A Morrisons spokeswoman added: "The store has apologised to the customer for the way that our colleague spoke to her as it was not acceptable.

“The incident and damage to her car is currently being processed by our claims department who have been in touch with her family to apologise for the time it has taken to respond."
