Worst service ever!

I actually do not even want to give even 1 star. Closed the account years ago. Could not sign off on line. Had to pay another month’s payment - which I did. Someone had to assist me still to unblock & close the account on line. I thought that would be it. Never used again. Still gets phone calls & daily sms’es, even after more than 2 years. When I sent an e-mail, to ask to please stop “harassing” me, the lady rep**** to just ignore, because they are sending these to everyone! What a joke. I now just keep on blocking the numbers from where these calls are coming from. Worst experience of service EVER.
