Consumer Redressal

i bought dishtv connection on 26th May and person installing it demanded money for wire.... now it has been less than 5 months and more than 20 times outages of channels and this wire has gone bad... they are asking for more money..... no compensation of outages.....person coming to do repairs is less than 18 yr old....no experience....asking for charges for connectors .......this is only interpreted as looting of customers. how they are making money is through selling wires etc.
