Simswap not working / employees not helping

On Tuesday 15 March I upgraded at Vodacom in V&A Waterfront, a sim swap was done. Wednesday morning (16 Mar) I received an error message \Sim provision #MM\". I called Vodacom customer care and was told the sim swap was not done, the call centre agent did 'n sim swap again. The sim started working after 4 hours and functioning for about 12 hours and I received the same error message again. Thursday evening I went to Vodacom at Gardens Centre and I was told all kinds of things by Darryn like upgrades takes days and it's normal for me to not have a functioning sim, my sim was linked to another number, V&A just wanted my money and did my upgrade before my sim swap, Vodacom has a new system. Eventually I was sent away with a sim not working and they told me it's not their problem to fix my sim swap because either V&A Waterfront or the call centre agent made a mistake. I've been a Vodacom customer for 17 years, this upgrade made my installment go with R400 and I'm sitting with a phone that doesn't work and Vodacom employees who states it's not their job to fix my problem."
