Renews contracts but cannot supply goods

I upgraded 8 contracts on Saturday 7 October 2017. The process took 2 hours. I was promised the devices on Tuesday 10 October 2017. Received a call stating that the phones would only be there next week (no date) and was advised that the ipad could take a couple of months to arrive. Had I been told this I would not have wasted 2 hours doing paperwork in the shop.

I also renewed 3 contracts that cost less than R40 per month for our security systems and was charged R 150 admin fee each. Had I been told this at the beginning of the renewal I would not have renewed as it costs me more to renew these contracts then if I had left them as they were.

I have been trying to contact the store to enquire futher and the phones remain unanswered. I see from other reviews that this is an issue going back quite some time.
