Keep decuting after contract was ended

<p>Indecember 2015, e-mail was send to ***, to have a contract cancled - 24 month period completed. I've received confirmation with a date 2016/01/16 and reference ***9</p> <p> </p> <p>In May 2016, I noticed that MTN still decucting the money from my account and I started the mailing process again. I've even tried phoning the office, holding for 12 min. I tried 808, asking for the Retention desk, but they can't transfer me.</p> <p> </p> <p>Contract ended 2016/01/16, simcard was deactivated and still I'm being charged monthly. I feel like someone is *****ing from me now. Everytime I've requested feedback from the Retention desk, I'm getting some automated response, someone will be contacting you. And when I do get a response, person did not read the e-mail.</p> <p> </p>
