Once again poor call center service Retentions dept

<p>I am due for upgrade and approached Cell-C regarding my upgrade and its been a week now with no joy.</p> <p>For about the past year I've had an unacceptable amount of problems with regards to call centre assistance.</p> <p>This has caused frustration with my account Surrounding payments and contracts not beig cancelled as requested on two other sim cards.</p> <p> </p> <p>My guess is that this is causing complications with regards to my upgrade.</p> <p>But not getting answers at all is a problem. They just keep promising to call me back and never do.</p> <p>One of these promises was made by a retensions supervisor.</p> <p> </p> <p>It's simply unacceptable.</p>
