Horrible upgrade experience

I had the most horrible experience with vodacom. I upgraded my phone online and my parcel was continously not delivered, vodacom was happy to blame RAM and request I contact RAM directly, it was only when I pointed out that I am a vodacom customer not a RAM customer that they attempted to resolve the issue. Everyday I was told delivery for the next day but this did not happen. This has gone on now for a week and a half. I was even told we'd escalate and contact you as soon as we have feedback. It has been a week since then and I've received no feedback. Today I got a message saying my package has been returned to vodacom. How does a person spend many days querying and arranging delivery only for the package to be returned to vodacom. This is horrible service, upgrades are meant to be exciting times, this instead has been a nightmare of an experience
