The mum of a disabled girl has hit out after a supermarket said it was unaware of its pledge to provide specialised trolleys.

Bonnita Moaby went into her local Asda store in Tunbridge Wells with her eight-year-old daughter, who has an invisible disability, to be told by staff that they didn't know about the GoTo Shop carts advertised on their website.

The 41-year-old, who is unable to drive, researched online to find stores that provide the specialised seats, which have adjustable headrests and a five-point harness to accommodate for a range of disabilities.

Her daughter, Amilie, has Sensory Processing Disorder, a condition in which the brain has trouble receiving and responding to information through the senses.

People with the disorder are often over-sensitive to things in their environment which can cause pain and be overwhelming.

Mrs Moaby said the trolley would have helped her keep her daughter calm while shopping instead of having to walk around holding her hand or sitting her inside it.

The mother said: "In a busy shopping environment it becomes very overwhelming for her.

"The trollies, the tills, the music, the people - it becomes too much and she will quite often try to hide somewhere or she will sit on the floor.

"It can be quite stressful and we get a lot of looks as if to say she is misbehaving because they don’t understand what she’s going through."

She contacted the shop ahead of visiting on Tuesday evening to ask if they had the trolleys, but there was no answer.

Instead, she decided to ask in-store where she said she was met by "blank faces."

The mother-of-two says the staff in-store and at the head office told her there was no demand for them and that there weren't any in-store despite the information on their website.

She said: "I was quite shocked that they had no clue what they were.

"I knew I had to make it more public because if parents don't know about the facilities available to them then of course there isn't going to be a demand.

"As a parent, I'm going to fight for my child to have the rights they are supposed to have.

"I have no doubt I am not the only person that would get a lot of relief when they go shopping."

An Asda spokesman said: "We would like to apologise to Ms Moaby for the GoTo shop trolley at our Tunbridge Wells store being unavailable but we can reassure our customers that we have replaced the trolley which will be available for our customers to use in the next few days."

Mrs Moaby said she will have to travel to Sainsbury's in Tonbridge if she wishes to use a GoTo Shop cart until Asda gets one.
