Vodafone India — sms facility stopped without reason

On 3/11/2018, my balance was zero, then from next day it started showing as -2.99, which was negative balance. When i complained about it to vodafone customer service, i got the negative balance cleared.
But the customer service executive gave reason for negative balance in my account, was negative usage charge for mms, but there is no record of such mms being sent from my mobile.in fact with zero balance no service can be used by vodafone subscriber, whether it be call, data, sms or mms.
So if vodafone customer care executive is saying that on 3/11/2018, i successfully sent an mms despite having zero balance in my account, then provide the records of the sent mms, such as recepient address.
Give proper proof of the deduction or else i am going to send this complain to trai (Telecom regulatory authority of india).
My sms facility is stopped without reason, i want it to be started immediately.in their e-mail, vodafone asked me to recharge with minimum 10 rs to start sending sms, but i had already recharged with rs. 398 for 84 days, so there is no reason for another recharge to start sms facility. Give me proper reason for wrongful sms facillity denial, or else i am forwarding this complaint to trai (Telecom regulatory authority of india).
