Tata Docomo — world worst services _ porting issue

First of all i want to highlight the truth, i am using world worst service, i. E. Tata teleservices ltd.

I had made request to port out with poring code (Tz313698) from docomo to vodafone on 29th june'18 after clearing my all due in fact i have made over payment before porting request. However my porting request is rejected due to outstanding balance.
I contact to docomo call center and talk to senior supervisor on 29th june
He replied i have no due and need to raise porting request once again, i do the same but while raising porting request again got massage as porting request is already open for this number (99703xxxxx), again called to customer care and talk to senior supervisor he replied he will close the porting code (Tz313698)
And i resend new porting code by sending sms to 1900.
On 30th june i resend sms to 1900 but got massage "your porting code tz313698 is already exists. I again call to customer care and again talk to senior supervisor and told him the conversation happen on 29th june between me and senior supervisor, he directly said i am telling lie and never talk to any senior supervisor. Again i called on 1st july again he said the same thing mention over. Again i called on 3rd july. And talk to senior he replied the problem is not from their end, i want to know if the problem is not form your end and my payment is cleared then why i am not able to port

I have all call recording. If you required let me know i will sent you.

Otherwise i have last option consumer forum
