MTS / Sistema Shyam TeleServices [SSTL] — Full and final payment done but again receiving the calls that your bill is due

Address:

Bareilly, Uttar Pradesh, 243006

I have made the Full and Final payment of MTS Data Card Number - [protected] in the amount of 717. But the payment has not been updated at their end since then, and I keep on receiving call on a daily basis from their Collection Department and I also receive messages on a daily basis from MTS to make the payment. I have been emailing them on a regular basis that I have made the payment and they are replying that they are looking into this but still they have not done anything. They also gave me my complaint number as but when I called customer care they told me that there is no complaint with this number.After all they say that you have to pay your payment of Rs 1187 . But i didn't used the data card because my number is deactivated because i have done full and final payment . It's a fraud company of fraudsters...
