I booked a parcel from Oddanchatram to Banglore at 1 p.m today. They got Rs 210 and they told I will get invoice through sms within 1 hour, but the amount is only for Rs 160. I waited till 6:38 pm and called the office, and now no one is picking the call, for what purpose they got extra Rs50 ? how can I trust hereafter ?
