MTS / Sistema Shyam TeleServices [SSTL] — Incorrect bill generated - spamming my inbox

Address:	580030
Website:	MTS INDIA

I had requested mts india to close my account, they told me to pay the bills, i paid all the bills and then requested them to close my account, instead of closing my account they kept activating and deactivating my account about with i used to get notification from mts. I contacted mts they told me that all customers are facing that issue so they told me the bill will not be generated and if it is generated by any chance they would wave the bill off. The next month till date they are spamming and threatening me to pay the fake bill which they have created which was generated because of their system errors. I have been telling that i will not pay a single rupee in all my emails to customer care.
