I have been using Deliveroo for over a year and rarely had a problem ordering food mainly in the City of Lodon (at a fairly central location). On 24 Dec 2018 however, I received three suspicious emails in quick succession from Deliveroo, one informing me that my delivery address had been amended, the next email saying my phone number had been updated and the third email saying my email address had been updated, all within 5/6 minutes. I was on my laptop so immediately knew someone had breached account security and was using my account to order food. Within 2 minutes I checked my Credit Card (details were saved with Deliveroo) statement and knew I had been charged 28 pounds for a food order. I immediately cancelled my credit card and called Deliveroo, who responded by email asking me for further information. Although I responded to Deliveroo within 10 minutes, there has been no response from management since. I was looking for a refund of the 28 pounds I lost because of poor site secuirty protocols, but that is the lesser issue here. The fact that the Deliveroo website would allow a user to make chnages to all three details (address number and email address) and still use a saved card / payment method is extremely dangerous. It is a serious system design issue and needs to be adressed asap. But since management is completely unresponsive I decided to leave a review online! Rest assured there is no customer service as such. Pls do not save any card details on Deliveroo.
