LazyPay — Annoying calls from LAZYPAY

Since from the day I used dunzo i started getting calls from LazyPay asking to pay the bill amount which i'd already to paid to dunzo in cash.
Informed the same to the customer care team over call so many times but still I am getting the calls from the customer support team.
Escalated the issue to lazypay higher hand Mr. Vishal even that did not work, dropped many emails saying that i've already paid the bill amount even received the reply saying that they've received th payment. I've also received the confirmation emails from both Dunzo and LazyPay.
Sent the screenshot and emails to Lazypay also but still am getting hell lot of calls asking to pay the bill amount and this is disturbing my personal life as well as professional life.
Please take this complaint and resolve as soon as possible

Humble request

Chaitra
