Data finished within 24 hrs

On the 3/11/2015, I went to Telkom at Bay Side Mall, & this was around 17:00 hours. After waiting for an hour for service I informed the lady that I had two problems. First being that I get 100 minutes & 1G data on the 1st of every month, I received my minutes, & I can't say that all my data was given to me, as in a space of less than 24 hours all my data bundles were finished, & the only social media I was using on cellular date was my Whatsapp . I explained to the lady about my problem &she advised that all IPhone 5's have that problem therefore should upgrade. She advised that she will open a case (Case Ref no: ***6), & that I will be contacted in 72 hours, &this was two weeks ago. The second problem was with my network, as I had ported from MTN to Telkom, &my network would & still is most of the time reading no network, &even though I am using Telkom, it would go back to the MTN network, & apparently she opened a case for that also (case Ref no: ***7). I still have yet to be contacted on the same case also. The consultant I spoke to was reluctant to give their names (Mbali Ntombela). I called again around 11:00 hours on the 17/11/2015 and I encountered the same issue
