R399.00 paid for 7 days internet connection only?

On the 20.10.2020 I bought my monthly 28 day base product voucher for R399.00. I came home and the internet was not connected. On the 21.10.2020 I called MWEB and escalated my issue to Vuma for feedback. After days and weeks I was then informed that my profile is in cancelation and that's the reason why my voucher isnt working. This was incorrect, as a cancellation for my recurring voucher was requested but instead Vuma just went and cancelled both the recurring and 28 day voucher profiles on their system. On the 10.11.2020, finally my voucher was activated, after calling so many times for escalation and feedback, wasting my money on daily data and my families, having to pay for a Netflix account that did not work. It took 21 days to get the voucher activated! How is this service??? Well it didnt stop there... On the 18.11.2020 I checked my phone upon waking up and AGAIN, my phone states 'Connected without Internet'. I then contacted MWEB and the matter was escalated as their systems agree that the voucher only ran for 7 days on my side... Now this is where is gets interesting! I reviewed Vuma's service on FB and got an inbox for assistance. I felt like i was getting somewhere. The person on the other end informed me that my voucher was infact activated on the 21.10.2020 and not 10.11.2020 and is no expired!!! I told them this is untrue and sent proof of my activation emails and sms's i received on the 10.11.2020 but was told to call MWEB, whereas they are awaiting VUMA's feedback. It's been 5 days and this is still not resolved. I am again wasting money and have to explain to my family whats going on. This is not fair and I want this sorted out. I paid R399.00 for 7 days? Please tell me how this work?
