Cellphone Complaint 2

I posted a review last week about my complaint I had about a cellphoned that was bought at the store. Their customer service phoned me the next day and said that they are looking into the problem and that I must please give them 24-48 hours. That was last week Thursday. We are on Teusday the next week and still no answer from them. If you phone the customer service deparment in Cape Town you only get to talk to a voicemail. When you try to phone the store in Highveld Mall you only receive a buzy tone.
