Vodacom Poor Service

On the 24/12/2015 I sent off my account cancellation forms to Vodacom cancellations, it was a basic 1GB data top-up package I had used up the data by the time I sent my cancellation request<br> <br> On the 26/12/2015 I had purchased airtime & Data for my phone as it was depleted.<br> On the 28/12/2015 I received a confirmation of cancellation of my account after this all the data & airtime I had on this number was removed by Vodacom the balance at the time was between 650mb-700mb.<br> <br> I contacted Vodacom because of this as it was not fair in any sense to remove any purchase made, loaded to my number, the lady from Vodacom customer care was seemingly very sorry, I could not accept the poor excuse of any account cancelation will leave me losing everything I had loaded on the number, I asked to speak to someone higher which she could not help me with and said she can only log this with her back office which I could not speak to either.<br> <br> I had made another complaint the very next day with the same excuse of a mysterious back office, its been a week and no refund or return call from Vodacom.<br> <br> I used to put Vodacom as the best service provider, this is the 2nd time they done this to me.
