Unreliable
Unreliable! Took my £11.89 for an O2 Pay-As-You-Go £10 top up and no credit ever appeared on my O2 account. Unhelpful in my attempts to have this corrected or a refund issued. Would never use again.

This company is a rip off
This company is a rip off. Hidden charge of 15% on a £20 top up. I was do ted to them by Giffgaff website and assumed it was a Giffgaff service. Then after getting a voucher number there is no obvious way to redeem it on the Giffgaff website who of course have no phone help and useless on website web chat. Disgusted with the Giffgaff service I asked Ontopup to refund the money having terminated my giffGaff account but they refused and it seems not possible to transfer the top up to my new provider, verging on deception. Would give no stars if this were possible. Cannot recommend for older analogue folks like me.

NEVER USE!!!
NEVER USE! I needed to top up in an emergency. Found out two months later I was somehow signed up for ongoing direct debit of >£20/month. Not clear or intuitive when arranging a top up in a panic! No one doing a top up could be assumed to be looking for a direct debit monthly top up -- that is not what a top up is for!
Everyone should read the Guardian article of 12 March 2025: Last month, my 84-year-old mother spotted a £47.56 charge from a company called On Top Up on her credit card bill that she did not recognise. When I looked into this, it emerged she had been unintentionally subscribed to a monthly mobile top-up service since September 2021 and had paid the firm just over £1,900. It dates back to when she asked her grandson to add a one-off top-up of £40 to her pay-as-you-go mobile. I assume that he Googled it and landed on a sponsored link for this firm, which charges a fee for the top-up mechanism – so a £40 top-up cost my mother £47.56."
Other complaints:
Unwitting Subscriptions: Many users report searching for their official mobile provider (e.g., EE or Vodafone) and clicking On Top Up's sponsored search ads by mistake. Customers claim an ambiguous checkout step causes them to unwittingly trigger a recurring monthly subscription.
Hidden Service Fees: Users have noted high admin fees added to what they thought was a standard mobile top-up.
Refund Delays: - Customer service responses regarding unexpected recurring charges are frequently reported as delayed or refused.
