Now I have Upgrade issues, what is wrong with you people? Does the nonsense ever end?

I am so tired of the ****ty service received from Vodacom. This time I am due for an upgrade. I do the process online and get a confirmation that someone will contact me within 24 hours. Nothing. I then phone you and get told no upgrade was processed. I then go instore to be told I cannot get the phone I want. You want to cap me at a ridiculous R400 per month, when I am spending on average close to R700 every month. I still then receive multiple messages virtually begging me to upgrade. After finally deciding to get a Galaxy S7 which is now two generations old at R399 per month, you STILL won't allow me to get that and want me to pay an upfront fee of over R5000!!! Are you idiots serious? You get your money from me every single month and now you want to treat me like this? Get someone with some brains to contact me to sort this **** out now. Phoning your call center is like trying to communicate with the dead. Shocking shocking shocking service and you should be ashamed. One would most likely get better service from Home Affairs if it were run by toddlers. I have complained on your Facebook page and still no response. ****ing idiots you all are. Sort this **** out NOW.
