data dispute

I'm not happy at all after a year's of great service from telkom. I'm using a postpaid phone with telkom i get one gig of data, 100 minutes and 5sms' for only R279. 00 monthly for 24 months. On the 11/04/16 I got an sms from telkom statimg:<br> You have 498 MB left of your Recurring All Networks Data. Dial *188# or login into [URL Removed] to get balance information.<br> about 15 minutes after that I got another sms stating:<br> You have 98 MB left of your Recurring All Networks Data. Dial *188# or login into [URL Removed] to get balance information.<br> <br> which really shocked me as I haven't used any data, my phone was off and the were no applications opened. <br> <br> and 14minutes after I got another sms stating: <br> <br> Your \Recurring All Networks Data\" bundle has been used up.<br> <br> I called the customer care just after that they couldn't explain to me as to what transpired and I was advised that a case will be logged. <br> case ref no. ***0<br> and promised that they'll get back to me within 72 working hours as i was on the phone with the agent i advised them to load 50mb and just after 5mins of loading the data i received an sms stating that it was also used up. I was in shock "
