Just say this post on SAAustralia concerning Keringa's prices. The post was dated 2 July 2007 :
I've just received an updated quote from Keringa Emigration and nearly fell off my chair!
They have increased their prices by 36% with effect from 1 June
I sent a query in March this year for my three cats and two dogs and was quoted R58 499.50. Last week they sent an updated quote of R79 879.74. Both are for a quarantine period of six months in SA, and exclude any additional charges and flights.
I phoned the kennels and was told that the increase, which came in last month, was perfectly justifiable due to their increased costs and the fact that they've installed a generator. Also made to feel like an imbecile for not understanding the fact that costs such as petrol have gone up!
So, either you cough up the additional (and do it with a grin on your face and be ever so nice to them, or they might not be nice to your pets) or make an alternative arrangements for your pets.
