A grandmother was left feeling "distressed and disturbed" after seeing explicit pornography on a tablet in a Watford supermarket.

Anne Jordan, 70, complained to the store’s manager and the customer service centre after seeing a number of sexually explicit images on the gadget in the Lower High Street store. 

However the Croxley Green resident is yet to receive a response from the supermarket and feels let down by the retail giant and their handling of her complaint.

After witnessing the explicit images on Tuesday, August 26, Ms Jordan sought out the nearest store member and the incident was then referred to another senior member of staff.

She said: "I was shocked. I did not realise how shocked I was until I was leaving the store and then I was angry.

"I just realised they had not looked after me. They should have said ‘are you ok?’ and made sure I was alright.

"I would have expected a proper apology.

"The fact they have not replied, even to say they are dealing with it is a reflection on their consideration for their customers."

But the 70-year-old described the store’s response to her complaint as "though she had returned a broken electrical item."

The letter, which was addressed to Dan McHale, store manager at the supermarket said: "I am appalled at what I saw, it was really unpleasant and quite disgusting, and goodness only knows what else was to be shown next. Who else had seen it, how many children, what if I had been with my granddaughter?

"It is totally unacceptable that this should happen in a family store, how come it was on display, had it been set up without parental controls? There are many questions to be answered."

"The apology was the same as if I had returned some faulty goods, not seen pornography on a tablet."

However, Tesco claimed that contingency plans were in place to stop visitors from accessing pornographic material while trying out the tablets in-store.

A Tesco spokesperson said: "We have filters in place to make sure unsuitable content is not accessible through Tesco wireless networks. We are investigating how this could have happened, and will take action to make sure it doesn’t happen again. 

"We will be apologising to the customer and will be sending her a small gesture to apologise for any distress caused."

The small gesture being offered by the retail giant is a gift card.
