Vodacom Cancellation Policies needs an URGENT review!

My family and I are in the process of emigrating to New Zealand. I phoned Vodacom to request my contract cancellation only to find out that you need to pay for your handset and then 75% of your data and airtime fees till the end of your contract. How ridiculous is this? I'll be in another country will have no use of any data/airtime Vodacom can offer me, still, I need to pay 75% of the costs? I then asked the consultant to please put me through to management so I can discuss the predicament I am in and if it would be possible to please make an exception in my and my husband's case as we have been loyal customers of Vodacom for many years! I was then advised that it will be referred to the "back office" and that the "back office" is unable to contact me as they don't do any callbacks? Seems like Vodacoms management is too good to speak to their customers directly if you ask me! You make loyal customers feel like just a number, you obviously have no empathy for special circumstances. I wish I was never a customer of Vodacom. On the other networks, you pay the outstanding amount of your device plus the current month's invoice which is more than fair! Vodacom needs to review its policies! No wonder they are ranked so low as a service provided on Hello Peter. I expect a call back from Vodacom management to discuss and sort this out ASAP!
