please help

I am so disappointed with their service,I have been calling them for the past whole week and even today with no help, my decoder has been disconnected even though I have paid them on time .I was told to send my proof payment of which I did, called them again after sending the proof payment they told me that they will allocate the funds and clear the error, that was not done. I called them again on the following day after sending the proof of payment but still the same thing happened ,the error was not cleared . Don't really know what should I do now because I have called them so many times with no luck of the error being cleared and each and every time when I call them these a new consultant and when asked them to forward my call to previous one they can't.they should just refund me my money since well they can't clear this error and wasp number is useless ,I have lost a huge amount of airtime trying to call them and having to hold for an hour while they try to clear the error.
