They failed to activate my debit order

I went to Tyger valley VODACOM and requested that my account be put on Debit order. I filled in the paper work and they sent me on my way.<br> After being oversees for 3.5 months I came back to a phone with no service. Enquiring they told me that my number no longer existed and that legal actions have been taken against me. Sim swap cost this and reconnection cost that (among other things/costs). After I paid only the amount outstanding on my account, I was given a new sim and told 24 hr then I'd be up and running again. 3 days have passed and still nothing. I have phoned the store and management every day and the wait for 4 days has today turned to :\reactivation takes 7 days."... WHO OPERATES LIKE THIS?! I am crippled without my phone and need to continue with my life in boxes and loads of things to organise. I am NOT a happy customer."""
