Vodacom - horrible service

Worst customer experience with Vodacom. I app**** for two identical black Friday deals, online.. One deal was cancelled without reason. I was not even informed of that until I called in. Then I was told that there was no stock and both deals will be cancelled and I was offered a 4g router instead for a 5g router deal for the same monthly contract fee.

I subsequently received an email stating that the original 5g router is out of stock and I'll receive another 5g router with one of the deals. The one that was not cancelled. While busy querying my applications over several days with Vodacom, via the Call Centre the IVR states that my number has been blocked, due to high call volumes from my number. How an I supposed to query my orders if you block the number due to your bad service? Blocking the number I'm calling from is an easy way to not provide a service to your customers. Especially after sales service! Very disappointing from a huge company like Vodacom!!!
