Very slow to put things right.
I purchased a top up yesterday thinking it would suit my mobile only to find it was of no use. I immediately contacted the support team as I have not downloaded a PIN - I could not do so as my mobile would not accept the top up - and have done so again 24 hours later. I have not even received an acknowledgement let alone the refund due and confirmation that any subscription has been cancelled. I've closed my account as a failsafe. Mistakes get made and a good company is keen to put things right. Clearly this is not a good company. How very disappointing.

They DO NOT TOP UP YOUR PHONE !
They DO NOT TOP UP YOUR PHONE !! They charge you £12 for a £10 voucher, they send email you a voucher number you then have to manually enter into your phone. Most other service 1) Dont charge you a 20% fee and 2) automatically top up your phone. I will not go near them again.

A trustworthy top-up company? I'm very unsure.
It was far from obvious to me that paying this company for a top-up is NOT actually paying the network provider. There seems to be a great risk of them making unexpected charges. I thought that I was paying Vodafone as I intended. How mistaken I was!
I will NOT be clicking the button in their email ,'Get Your Top Up' as I do not believe that it is safe and can be trusted.
I hope that I am wrong.
It would be better if this company's trading modus operandus was far more transparent.
Perhaps others have had very satisfying experiences but I will certainly not be trading with them again.
