SADV IS A ****

I paid for the installation for wifi last year in April, they have never pitched, I kept checking on them for update and I was told that they made an error and they will rectify it. I even moved from that place and still they didn't pitch. Im trying to get my refund and I have sent them my banking details, and again I was told that there was an error while trying to capture my refund. Im so disappointed, disgusted and angry, SADV is a **** that takes away people's hard earned money and dont they deliver. PAY BACK MY MONEY!!!
