Terrible service regarding upgrades, lying call center agents and terrible attitude!

Seriously unimpressed with telkom! I called in to upgrade my mobile contract last week Monday, I was told that the phone I wanted was out of stock but the "special" was ending on that day so I settled with a phone I wasn't going to choose. Only to see the special is still on one week later! I completed the upgrade order and was told I would get an sms on that day or the next. I did not, I finally phoned in on Friday to be told it hasn't been captured their side and its been escalated and that I should get an sms by Saturday or Monday morning. Still nothing. I called in and was told there's no updated info and that I must be patient but they can't tell me if it's 10 days from last week or if only 10 days from when I receive the sms? Phoned again today (Tuesday 1 week 1 day after order) to find it's still not been captured. So my order will be delayed further. Tempted to cancel my order and both contractsand upgrade elsewhere.
