Poor Service

Last night around 10pm I had airtime to the value of R289.00 and my data bundles were depleted. I purchased data of 155MB and did not use my phone until this morning when I was on WhatsApp for a couple of times. I have just checked my airtyme and noted that all my airtime including data bundles were depleted. I called MTN and spoke to Mandy who advised that I was streaming videos hence my airtime and bundles were depleted. I requested details regarding the websides I was on as I have not used any internet applications on my phone since last night. I was told that I will be transfered to Steve Govender to assist and I have been on this call for almost 30 minutes and Im still holding!!
