Explora deal gone wrong

I ordered the Explora R899 bundle deal and after waiting 3 weeks for the debit order to go through I had to wait another 2 weeks before installation. When that finally happened they linked the wrong decoder to my smart card meaning that I have no PVR functions (pause,record,catch up etc). After spending many hours on the phone with multichoice I keep getting promised that someone will call me back and the problem will get fixed. To this day no one has called me back and my decoder is still not working!! I am fed up with the service you have failed to give me and if this problem is not fixed within the next 24 hours you can come fetch this decoder and cancel the subscription as I refuse to pay for something not working as it is advertised 100 times a day on DSTV.<br> It seems like no one at the call centre knows what is going on and keep referring me to the self service on your website - even after trying that more than once it does not pick up my smart card number and is also not linked to my cellphone number?????
