Unhappy with Multichoice

I have just moved back to SA from Botswana. I brought with my two decoders thinking I can change the country and use them in SA. Multichoice Botswana sent me forms to fill in and the decoders were put into secondhand status. Multichoice SA, which I did contact, said that I had to purchase a new decoder, have an active account with an active package which I did. Now I get told that the software cannot be changed from Botswana to SA. I have spent time and money on phone calls, emails. Multichoice needs to inform their customers with the right information. I sit with two explora decoders that I cannot use. Now what?I have been a customer of Multichoice for a good 7 years without any problems until now. Very frustrating and disappointing.
