Threatened with SNC because I amended order

[chrisc 10]

Seller states Free Collection from shop in Cape Town in his ad.  

Tried to find out approximate location, so I would not have to drive for hours to get there, but rather pay for delivery

Seller ignores two questions

Contacted Chat.  They said I must place an order, whereupon sellers contact details would be visible.  They are, but still no address.  Two phone numbers, one does not exist, second "try again later".   Sent email to given address.  No response

Contacted Chat again.  I must pay they say.  But I explain, would rather pay for delivery if its a long way off.  If you do not pay, there will be a SNC against you

So order again, this time choosing delivery.  First order is not cancelled.  I am unable to amend it

So much bureaucracy and poor communication drives me up the wall

Why not make it easier, for heaven's sake?
