No feedback on data query

<p>I logged a data query on the 22nd of September. I got an sms that it has been escalated to a support specialist, ref number 1- ********** 4170. Although Vodacom promise to call back in 48 hours (I thínk that was the timeframe), I haven't heard from them. I phoned 3 times to follow up why they didn't return with an answer. The first time I called the consultant asked me why don't I wait another day and see if they come back (that was on the 28th). The second time the consultant tried to put me throught to the correct dept as he said they don't have a direct line for clients, but it got too late and I had to cut the line. The 3rd time I called the consultant also tried to put me through to the correct department, and I suggested that she just asked them to phone me and she promised to do that. I also keep all my recordings. Until today nobody called back. So now I want to know - do I have to take annual leave to sort this out? </p>
