E143 error

I have been struggling with dstv for the past 4 to 5 months and I am tired. Their solution is that I must disconnect my decoder and connect it again. I have two decoders, a primary and a secondary decoder. My secondary decoder hasn't been playing. I've been calling and they couldn't find the problem and I was advised to go to the dstv outlet. I went there and according to them everything is fine and the decoder is OK. I realised that the secondary decoder number on the general information when I check it's incorrect on my side so when I sent the heartbeat to the secondary decoder its going to a wrong number. Hence I am getting e43 error code on my secondary decoder. According to the call center they have the correct one but on my side it's showing a wrong number which they also don't know. They can't link my correct number so that it reflects on my primary decoder in order to connect my primary decoder to the correct secondary decoder. When I ask to speak to a team leader they put me on hold until the call drops. Today I spoke to nolwazi, ronel and nontethelelo.
