Tata Docomo — porting request rejected

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 ([protected]), 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 problum 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.

Thank you for providing world worst services
