Paying for a device I don't have !!!!!!

I took a laptop from vodacom on contract. The laptop was faulty so I took it in. They had to replace the mother board but it was still faulty. Ibten requested a new device as my wife uses this device to work. I have been struggling with getting a replaced device since August. Right now I am paying for a device that is not in my possession. My household has become a 1 income home because my wife cannot work. She teaches online and has lost so many opportunities. I was recently diagnosed with lupus and this problem as well as the financial implications has affected my health. As I write this review I am in hospital. I have sent numerous emails to srm, shameel joosub, rudzani Lithole. The last communication we received said that we must go to the vodavom store as credit has been loaded. We did that only to be told there is no credit loaded. Since Friday we have sent emails asking where is the credit but everyone is ignoring us. The next step is to take this to the Ombudsman. This affected my health, my financial status my wife's job and I am paying for it but I don't have a device!!!!!!!!!!!!
