Dissapointing Service

On 16/04/2016 I app**** for a modem contract online, almost immediately I received an email saying the contract was approved, however I still called the online store to confirm this. On 20/04/2016 I made a follow up call because no one from Vodacom had contacted me yet. On that day there was a problem with the system and a lady promised to call back and didn't. The next day I made another call and the order was completed with a lady by the name of Kim, who is all honesty was very helpful. She completed my order and advised that I would receive a confirmation call the next day.... that never happened. Since then, and 3 weeks later, about 5 DM's to the Vodacom customer service twitter page, still no joy. I get calls from the social media desk promising people will call to confirm the order. All I want is for the order to be confirmed and on it way to me or if there is a problem, let me know and I can move on... I cant understand the delay. I understand that there are processes to be followed, but how long does it take to confirm an order, maybe I should have been advised on the waiting period for the confirmation call when my order was completed, but to wait 3 weeks and no response unless I follow up is a bit ridiculous, not the kind of service you expect from SA'S leading service provider. HIGHLY UPSET. I'm not yet a Vodacom customer and the service is already bad.. is this how you welcome new customers?
