Unable to migrate to higher package

<p>Took out a LTE powerplan 25GB contract 2 months ago. At the time the Sales Dept informed me that I would be able to upgrade to a higher package if I want to at a later stage.</p> <p>Earlier this week I contacted the Sales Dept to ask to upgrade my contract to the 50GB package. They said I need to contact the Migrations Dept. The Customer Care centre, who I ten got through to, logged a call for the Migrations Dept to phone me.</p> <p>The Migrations Dept phoned me today. I spoke to a lady by the name of Funa. She informed me that there is no option on the system to upgrade from LTE powerplan 25GB to a 50GB package. She would have to escalate this to the Sales Dept.</p> <p>I told her that the Sales Dept already told me I had to speak to the Migrations Dept. She said well she can't help me and after a a bit of a pow-wow between her and I she put the phone down in my ear.</p> <p>This is TOTALLY UNACCEPTABLE behaviour from a service provider.</p> <p>And I now still don't have the upgraded package.</p>
