If zero rating was possible...I would have given Lyca that. Very rude customer service. We have had a Lyca SIM for 6 years and used on and off for international calls mainly. Even bought air tickets through their Lycafly. Also used their money transfer service, and even considered transferring to Lyca full time for UK mobile service....How did they reward that loyalty?Took money but reallocated number without warning, though they claim they did. No refund, no apology, no nothing...won't even let you speak to a manager. Dreadful service and will not be going back there for anything in future..
