Same thing happened to me also I have a personell loan too with Doha Bank with out my knowledge they have deducted more interest this time, when i send email to them they replied saying that they cannot assist me I have to personelly visit the branch from where i have taken loan, this is ridiculous,if they keep increasing the interest rate like this I wont be able to pay off the loan at all and may be it will take very long time and moreover how can they charge us without any justifications one fine morning they decide to charge 25% interest rate..?
