Should I Really Renew My Contract With Vodacom???

Firstly I pre-ordered the Sony Xperia Z5 via your online ordering system on the vodacom website. I eventually get a call from a consultant confirming my order. I specify to the consultant that I want to change my contract from a Smart L to a Smart S. This is when all the trouble starts......<br> <br> The consultant says that they have to cancel my initial order and redo my upgrade to change my package to the smart s. I agree and was promised a call back to finalize the changes. As you can expect I don't receive any feedback and I the consumer who wants to renew my service with vodacom has to request feedback with back and forth promises that I will get a call back<br> <br> This morning Sharon calls me from your online department To tell me that the upgrade was reversed. Then she says bye and I ask her aren't we going to do the upgrade now?<br> <br> So, Sharon says ok??? Almost like she is doing me a favour. <br> <br> I then ask Sharon am I not going to get a new sim card? She then proceeds to asks if I need one and I say she is the one that should advise me ****** and eventually she realises that I will need a new sim card.<br> <br> My question is should I really renew my contract with Vodacom given this poor service
