LazyPay — Harassing me on wrong bill/invoice

They started calling me for payment of some transaction on 12 jab of amount 159 through confirm ticket. I have spoken to confirm ticket customer care, no such transactions took place from lazypay. Now they started harrasing me for payment and late fees of amount 212. Amount is less so I ignored for sometime. Now the frequency is increased and they shout on calls. No such bills and invoice was produced to me till date for this. Need to raise a dispute urgently
