At first I got an sms from 1552 saying about 888 naira was deducted from my account.then I loaded a card,checked my balance,my account was zero.I then called customer care who told me I must have made calls for free.I asked them to tell me when,they couldn't.they even told me I'm still owing some certain amount.I asked to know how much,they couldn't tell me.I hung up in annoyance and checked all my call logs.I'm sure I never made any call for free.I loaded another card now and still they deducted it to zero account.this is cheating of the highest order.isn't there supposed to be a body to tackle this kind of illegal extortion from these telecom ops?and I'm sure I'm not the first and won't be the last person this will be happening to.but how can they do this and get away with it.this is fraud!
