How do you treat new business like this?

How is Vodacom's service still so poor?

I filled in my details for a new contract on Thursday last week - it error'd out after putting in my ID Number and Cellphone number - I was told I'd be contacted within 24 hours. Nothing.

I tried to get help via Facebook messenger - kept getting asked for information I'd already provided. (e.g. a screenshot of the deal I was applying for was requested directly after I provided the screenshot).

Eventually I was told I'd be contacted, again within 24 hours - I received an email and sms to this affect - again nothing.

How do you treat potential new business this way? Vodacom is my preferred network for coverage - but today I apply to other networks.
