Appalling service!!

Good day, I visited Vodacom at Marko Springfield on 22/08/2020 and wanted a cellphone Contract with Vodacom . I was helped by Miss Mhlongo. I wanted the iPhone 6 s deal for 299 but I settled for the iPhone 6s Plus for 229 each and I took 2 phones since I love the plus more.I was approved for the deal for these two phones for 229 each,the lady then tells me that the iPhone 6 Plus X2 is now going for 299 for both. I was ecstatic coz that would mean I am saving R160 and she said if she changes to that deal it will drop my credit score and I might not qualify for it.I was disappointed because I know your credit score does not drop in one day and the price is quite less,nonetheless I took the phones for 229 but I was not happy. I then went to another Vodacom shop to enquire. I was then advised that it is possible for the deal to be canceled and it can be processed for 299 and I still keep the same phones, just that they can’t help since I didn’t purchase it there and was referred back to Springfield. I went again to Springfield today and waited quite some time to be assisted and I told them that I want the 299 deal for the same phones. Bare in mind I have now transferred my applications to this new phone and I paid for doing that which I don’t mind. I was advised by Rico a manager ,who got confirmation from his superior Vijen that they would need to cancel the contract and reprocess it on the new deal and it takes 2-3 days but they will need to take the devices incase that deal gets declined. I was rather appalled by the service I got as I did mention that I am currently using the new phone ,have transferred all my apps to this new one and sold the old phone so this means I will be phone less for 3 days but it didn’t take that long for me to get the phones . What puzzled me was how can the deal be declined whereas my credit score is good,if it wasn’t then It would have never been approved from the get go and if the lady that assisted me did the 299 deal same time It would have saved my time and petrol instead of speculating that it might be declined. I’m a first time Vodacom customer and I must say to say I’m disappointed is an understatement. I will NEVER recommend Vodacom to anyone. The service is absolutely poor and customer expectations are not met.
