Very poor service

Bought a new decoder as the one I had,had a water damage Phoned multi choice on the 4th trying to link the new decoder with the old one as I have extra view I spoke to about 5 consultants who promised to continue linking the decoders even if i got cut off Each consultant took more than 30min keeping me on hold I spent about R200 of airtym calling I den did the self service on watsapp The chat board said the decoders are linked and that I should contact my installer I tried again yesterday with the chat board because my installer had assured me that everything is ok on his side So yesterday the chat board said my decoders are not linked they sent a link which doesn’t go through Wat does it take for one to do a simple thing like linking a decoder? How much more airtym do I need to spend ?
