6 Months and still trying to resolve the same issue!

<p>about 6 months ago i migrated both of my plans from smartplan 50 to smartplan 100 and was told that it wouldnt start a new 24 month contract by the store, call centre and billling department. Then last week i realised that it did start a new 24 month contract! Logged a case a month ago - no one contacted me reagarding it and i was adivsed that the case has been closed to we made a new case... then they say they tried to call me but i was unrrachable! No mkissed calls or voicemail on my phone, complete and utter incompetence!</p>
