Bad customer service

I tried to get help from the call center to find out if my sim was still active. First time around the consultant could not hear me and it ended to be a 5min back and forth of "can you hear me". When we could finally hear each other she said repeatedly said that I must phone from the number in question after I explained twice that I could not do that as I could not connect to the network. Eventually I asked her if I could give her the number and that is when she said that my sim was still active. Then she could not hear me once again and then dropped the call. I still could not connect to the network after this call. I decided to call again and this time around the consultant and I could at least hear each other. He proceeded to tell me that my number had bee recycled and was in use by someone else. So yes, it was active, but for someone else. I have phoned this number and it doesn't go through to anyone... I understand this, but I still needed to ask some questions bout RICA etc, however he didn't give me a chance and proceeded to basically put the phone down in my ear, he did not even attempt to ask if there was anything else he could help me with. Twice in a row not very great customer service.
