Horrible Service

On the 28th of January I received an sms notification to let me know I will be rewarded with 1gig of data and all I had to do was keep my sim card in my fone for 3 days. Needless to say, this has not happened. On the 09th of February, I call Vodacom customer service to find out why I have not received the data as per the sms received, and they very politely told me they could not trace this sms that was sent to me. The guy I spoke to promised me he would have their technical department trace the sms the following day and they will provide feedback to me. it is the 17th of February, and not one was competent to give me feedback regarding the data is was supposed to receive. this is horrible service!!!
