Very disappointing experience with doctorSIM.
I entered a UK mobile number on their website, and their system identified the operator as Vodafone. I relied on that information and purchased a top-up for €13.69.
After receiving the recharge PIN, it became clear that it did not work. I then confirmed that the number is actually with **Lebara, not Vodafone**.
I explained this clearly to doctorSIM, including that their own website had identified the wrong operator. Instead of taking responsibility for the incorrect operator identification, they told me that the Vodafone PIN had already been issued and therefore could not be cancelled or refunded.
They also did not provide a replacement PIN/top-up for the correct operator.
The problem is not simply that I selected the wrong operator I relied on the operator identified by their own website. If their system incorrectly identifies a phone number as Vodafone and then sells a Vodafone top-up based on that information, I do not think the customer should be left out of pocket.
Customer support kept focusing on the fact that the Vodafone PIN had already been generated rather than addressing the underlying issue: their website identified the wrong network in the first place
I would not use this service again and would advise others the same

Doctorsim is a fraudulent site,I will advise you guys to be very cautious,all the times I tried using doctorsim,I was debited but my airtime was not delivered,the last experience I had with them some days back,I tried recharging and I was debited but didn't get my airtime,so I sent a mail to their customer service,they replied that my money will be refunded,it got refunded then all of a sudden I got a debit alert from doctorsim that I didn't initiate, apparently they store customers data and use it,guys doctorsim is a fraud,I have not received my money back up till now. So better thread carefully.
