Deceiving prices

I bought an explora on the 13th of December asked a local accredited installer to do the work for me. He called the call center notifying them that I've upgraded, he had a lengthy telephonic conversation with the call center agent verifying the numbers on the decoders, it was then connected. last Sunday I received a message saying that my account has been suspended, i went to multichoice jabulane mall I was assisted by Kgomotso who told me that i need to pay in order for them to reconnect my dstv, i told him that (Lorna)the center agent that was assisting with connection of explora assured us that I'll only pay on the 7th of January now they are changing the story. Today again it was disconnected and I'm suppose to pay R857 multichoice is deceiving us. And i don't get any assistance whenever I'm calling the call center. This morning I asked a lady from accounts to call me back after having had a lengthy conversation with Thami guess what she didn't call me. I'm a customer here and i deserve better service
