Ufone money deducted from account

#1
I made a Rs500 recharge in my Ufone mobile account 3 days ago, and when I checked the balance today I am left with only Rs300. I have not used my phone at all in the past couple days and used my 3G connection but only for like 10 minutes. Do you guys think I would be able to get the lost money back and if so how do I go about it?

Make sure you remember the dates of recharge and the date you checked you balance as you would need to tell customer service about this. The deduction amount is quite a bit, so you my need to make a couple of calls to get your money back if it is not done in just one call.
