I have very very bad experience!! from to day i am leaving them.i am changing my SIM from lyca to Lebara this private company Lyca Mobile are making a lot of money by charging {stealing} us more money from from poor people , and they are well on UK no one investigate them. I am one of their victim. from 2015 I was using Lyca happily but from time to time lyca company they start changing their caracter . for example nowadays if i top up £5.00 pay as you go ,if i spent only £1 after that if check my balance already gone, this is happening many times i called customer service they gave me only reference number for the future but they never refund my money and they never solved out the problem they said only ''sorry to hear that'' the UK Government must investigate This private company of lyca mobile.Thanks.
