Last port of call for Vodacom

I went to Vodacom for a new contract and to port my number from Cell C on Thursday last week. Each day I was told there was an issue with porting until eventually on Tuesday Vodacom came back and told me they now require a copy of my ID and 3 month's bank statements. Why the hell couldn't they ask for that on Day 1 if my driver's license was not sufficient. Meanwhile I had given my old phone to my son as I believed it would not take longer than a day. I asked them to cancel my application, and I went to MTN instead where I got a great deal, but I cannot port my old number, as Vodacom still has the number locked with a "Port Pending" request. Numerous visits/emails/etc has not resolved the situation, and I am still without a phone for a week!
