Vodacom can't perform a simple SIM swop

Vodacom,vodacom...... What a useless bunch. Long story short my dual sim phone was ******, went to cellc to do a swimswap 15 minutes later sorted. Went to Vodacom it's been 3 days and still no joy. I have been in store (apparently they can't verify me - even though on my app and online profile the number is linked to my account) I have tried phoning 082 135 (don't waist your time it is a bot and no intelligence behind it - asks me for my new SIM nr I enter it sorry we don't recognise the number) Tried the chat option agent says they can't perform the task. And nowhere is there an option to speak to an agent
