EMPTY PROMISES AND NO CALL BACKS

I am at my wits end with Supersonic. Been trying to get my WIFI on for 7 days now. I have made 9 phone calls and everyone promises that my Internet will be on that very day and everyone promise to call me back but they don't. I was told to make an internet payment to Supersonic to the bank account on the invoice, only to be told the next day I shouldn't have done that, now there will be a refund due... Then I was asked to pay via paypal which I did 3 days ago and was promised once the payment is through I will be switched on. I called yesterday again and spoke to another consultant who promised me I will get my log in credentials and I will be online. I called again today only to find that they had my incorrect cellphone details (I don't understand because they called me on my correct number yesterday) I was promised that I will be called back before the end of the day today and I will definitely be switched on.... im still waiting???? Can someone who knows what they are doing and is committed to satisfying customers please call me back, I have paid for a service that I don't have yet.
