My request was approved online in four days - although this was after I had been requested four separate times to upload the same documents.
My partner was asked to visit the sales office with the documents. The sales office had never come across this before but having been shown the TK email they duly copied the required documents and sent the pack to TK HQ. After nine days, no response. So it seems to be ignored rather than rejected/approved.
Was there any difference between your activity or the type of documents you've originally submitted? Still trying to figure out what the key is here.
