MTS / Sistema Shyam TeleServices [SSTL] — Unethical Behaviour

Address:

Chennai, Tamil Nadu

Hi,

I was using MTS data card. with no [protected].
I want to discontinue my usage and i called them for deactivating my card. They told that i have outstanding amount and if i pay they will discontinue the service. i paid the outstanding amount. Again teh next month they generated bill. i also paid that and asked for discontinuation of service they agreed. the next month again they generated bill. i called customer care and asked once again. they told if you are paying outstanding amount i will deactivate. so this time i paid and asked mail confirmation. they sent mail and i paid. and now i am getting mails and messages asking to pay 100 rs. else action will be taken.
