Upgrade woes

Hello, my name is Viwe Nyoka, a loyal customer of Vodacom for the past 10 years or so. I emphasize loyal because I have used other networks over the years bit still kept my Vodacom number through them all. From the days of the S3 to Note 5 i have had a multitude of devices and contracts with you. Today i have learnt that loyalty is not something rewarded by yourselves - I guess business is just business. My last contract with you expired at the end of 2017, but I kept it running as I was happy with what I was getting . Now to put this in perspective, multiple times your agents have called trying to get me to upgrade but I refused as I felt I still had functioning devices and would only upgrade when I needed to. Well this week my current device started giving me issues and I decided to finally upgrade my contract. By the way, I forgot to mention that I have 2 contracts with Vodacom and both have expired. So this afternoon (2018/12/02), I went to your shop at the mall of the south to upgrade. To my dismay I was informed that I would have to pay in R3500 upfront. On questioning this, I was informed that my profile was low. I subsequently left the shop with my tail literally with my tail between my legs..... Still looking for answers, I called your upgrades call center to enquire more about this. I was informed that since i was no longer paying my account via debit order I had to pay for the device upfront. Now let me be the 1st to admit I have been late paying my account a few times but it has always been paid. Well kind people of Vodacom thank you for taking my money for all these years, I think now is the time other providers get a piece of the slice. I know my monthly payments are not even a drop in the ocean compared to the rest of your client base. To say I am disappointed by your treatment today would be an understatement of the millennium. As such, I will be porting my numbers to a different provider at my earliest convenience. Maybe, just maybe they will be more willing to assist. Thanks vodacom, thanks a lot for reminding me it's just business, nothing personal.........
