Extremely bad service in stores and call centre

<p>Latoya Parka apparently a "manager" in the Telkom call centre assure and re-assured me she would contact me back several times to give me feedback as to why my account has been cut,it has been 2 days now and after several attempts of having to call in to speak to her or her manager they are all in a "meeting". I have been a loyal customer for the past 3 years with 3 different contracts and whenever I needed assistance in store and at the call centre the service was bad!!!!! Extremely disappointed,can I cancel my contracts with them?</p>
