Poor Service

Bought the wrong set of Bulb online,Which I admitted, Then tried return the Product of which was informed of no returns on this specific product,They then Agreed to return on the basis of testing the Product which I accepted and I even paid for the Courier service to collect and then deliver the correct product once tested, Its now been 3 weeks still waiting,even received the way bill but still nothing, Really disappointed and frustrated at the way this process is unfolding.Really poor service
