Spoken to ebay customer service, Rochelle then Srinivas.
They have unilaterally swapped x78 (inferior model: 2g, single camera, flip phone) instead of Q80 (superior model, 3g, dual camera), and they expect me to be happy with it.
They have the gall to insist that x78 is more expensive than q80.
Finally, he has ended with the equivalent of "do what you want", ie, put consumer case if you want. He has further refused to give the postal address to which the legal notice has been sent. He has refused to put the change on record.
VERY BAD SERVICE, practically cheating, in fact.
I am approaching consumer court for this, and I will claim damages, punitive damages, costs and harassment.
