No reference number or feedback call

On Saturday, 28.03.2015 I called Vodacom 114 number, I spoke to Pretty whom I explained my problem that might be the cause of NOT being able to receive MTN calls on my phone, after a prolonged conversation and clarity to her, I asked for a call reference number, however Pretty confirmed with me that she will sms it, and that today, 30.03.2015 their technical dept. will give me a call, it is almost 19h00pm and still no reference number, no call to resolve my query
