Failing to complete step 4/5 multichoice installation wizard

I received a message to pay my monthly subscription fee to avoid being disconnected. I paid with an extra amount. To my surprise when I switched the tv on am disconnected. I sent them email with proof of payment but the whole day gone no connection. Tried to watch tv I have a installation wizard when in step 4/5 a notification box comes telling me the task can't be performed due to signal strength. Am really frustrated. What can I do guys
