Consumer Redressal

I paid Hathway for installing wifi connection in my house on 4th Feb 2014, when they came for installation they said i will have to pay extra for wifi connection and for the amount i paid i will get LAN connection. I did not want LAN connection hence i cancelled my subscription. They informed me i will get full refund of my amount. Have been calling their customer care center since past one week now, everytime they say they will make their billing department give me a call about my refund query. Its 19th Feb today and i haven\'t received any call from them regarding refund nor have i received the refund. The receipt number provided by them is as follows: SLRISP/38576
