Really bad customer service --- I am currently in Singapore and unfortunately using a clay international SIM.. Despite endless calls to their customer care, there is no help from their end. Now i domt have data working on my phone, which i have ready paid for, but there are serious issues with their local network as wrll...   Not only have they disconnected the data on my phone, but the voice calls as well. Reason being that I have crossed the limit. Well I didn't know when I signed up for that...
