"I'm a very family-orientated person. It's so childish of them to do this, it's embarrassing. I'm utterly disgusted with what has happened and how I've been treated. I want people to know what they have done."
We annoy customer service staff at our peril - and they often take revenge. Sometimes, it's very direct, such as the time an EE call handler emailed a customer calling him a 'f*****g c**t' after the pair had argued on the phone.
Often, though, they hit back in the same sort of sneaky way as the O2 worker. This time last year, for example, an Amazon customer who had previously complained about customer service got a surprise when he logged into his account - a ten-inch sex toy had been added to his shopping basket.
And insulting names are often added to restaurant receipts - and discovered by the victim. A Pizza Hut customer was described as a 'pink fat lady' in 2014, for example, and three women as 'fat girls'.
In this latest case, O2 has apologised and offered Aaisha £75 and the chance to upgrade her handset early. But she says she has still contacted the ombudsman to try and make sure that the same thing never happens again.

Early Lewis from Detroit was amazed to find his water bill was almost 100 times as much as he was expecting. The bill claimed that Lewis had used 3,740 gallons of water in just one hour. Thankfully common sense prevailed and the Water and Sewage Department admitted it was a mistake and subsequently charged Lewis the $36 he should have been charged initially.

George MacIntosh, 73, was charged a staggering £200 for premium-rate gambling texts he didn't intend to sign up for. Unfortunately this wasn't a scam but a legal service from a company called Zamano.

Philip Groves was amazed to receive a £1,411 bill from Vodafone last year for his 10-year-old daughter Trinity's phone. It turns out Trinity had watched 28 hours of instructional loom band videos on YouTube, assuming her phone was using wifi.
