Dear sir,
I purchase first time to fly by spice to jeddah - hyd round trip
By pnr. U9l2wp.. When i change date of my wife booking for other date taht pnr. Kyw2yf paid amount rs.4100/ then i got message your transaction amount paid to spicejet. But your staff informed me to system error we not recieved your payment pay again then again i paid rs.4100 on 9th may 2019 and my bank also informed me that your payment crdited to spice jet.
So first time when i was travelling i am facing this problem now next time i dont want to travel nor recommend others to fly by spice jet..
So kindly look into the matter and refund my amount rs.4100.
