Failure to cancel services after numerous requests

<p>Hi,<br />I called to request services being removed from my subscription, such as a data bundle and SMS bundle. This was not done the first time, and when my bill arrived it was still there. I then called again on 1 November to express my dissatisfaction and was assured it would be rectified, reference number for the call Ref : 1- ********** 7748. I received no follow up and no resolution. I just received my next December account and once again the services are still being billed.</p> <p>This is totally unacceptable when I have requested to cancel them. Please assist me with this asap.</p>
