Upgrade

I did a upgrade on 6 June for a Redmin Note 11 Pro the lady i spoke to was Vanessa she told me there is stock on hand and my order was placed everything was done and i,would receive my phone with in the next 2 to 5 days. Friday 10 June i phoned to find out why i haven't heard anything from Vodacom i was told my order was cancelled???? So i had to go through all the stuff again to upgrade. I phoned this morning now I'm told there is no stock???? This is pathetic service by Vodacom and if this is the way they treat customers I'm taking my business somewhere else.
