data depleted within minutes on whatsapp

<p>I am beyond irate!!!! I called the call centre spoke to a guy named Zama and explained to him that I bought 250megabytes of data and they depleted within 10 minutes. I then purchased 100megabytes and it depleted within 5 mins. I told him that I had not logged onto facebook, I dont have instagram and my apps do not update in the background because I turned that setting off. I had only been on whatsapp chat, no media, voicenotes or video etc. This should not deplete data so quickly. My data usually lasts more tahn 5 mins. He gave me a reference number and said their technicians will investigate and get back to me in 48hours. This was on Saturday morning at 10:15am. It is now Wednesday at 13:15pm and I have not heard a word from Telkom. I am appalled, especially beacuse this is not teh first time I have had this experience with Telkom. I demand to be assisted immediately and compensated for my data. This company is ripping me off and I am inclined to take further action if this matter is not attended too. </p>
