Faulty Prepaid Metre

I am a tenant at Jabulani Life Estate Block F unit 205. The prepaid metre has an error 30 and when I try to insert the token number to load the electricity it does not accept it. I ran out of electricity Sunday morning and today it is Thursday: I have not received any assistance unto this day. I have sent an email to customer care and they have advised that the matter has been escalated. I need a new prepaid metre urgently. My groceries have spoiled and I don't know how I will survive until month end. How long does it take to replace a faulty metre? I will not recommend anyone to rent at any properties of afhco as they do not care about their customers.
