Dnld deals mydala 99-mydala

Amount of Rs 99 has been charged by vodafone on the name of mydala without any information and permission.
i never opted for such kind of any services. Im surprised how the amount will get detected from my main balance…instead it should ask for the credit card or debit card…I see there is no security for the amount to keep in the Vodafone network…some how they are miss using and taking the amount…
