Full of Excuses

I have 2 data bundles on my phone and my data is coming from the last one I purchased. I phoned 155 to enquire on 13/08/2015. After spending 43 minutes on the phone I received 2 different explanations as to why this is happening. 1st- Your second bundle was purchased on promotion which is used first- no it wasn't. Then I was told that it was because of the file size of my downloads. The consultant told me that my first bundle was last deducted from on 09/08/2015. Do you mean to tell me that EVERYTHING used on my phone from 09-13/08/2015 was more than the 180mb available in my 1st bundle? This bundle is due to expire today and I am going to lose 182mb because of Vodacom's technical issues. This is unacceptable!
