Blacklisted phone

I was owing vodacom for a few months because of a financial problem which resulted in my phone being blacklisted and my line disconnected. I made an arrangement to pay my account and I honored the arrangement and fully paid the amount I was owing, I made the final payment on the 9th of November 2020. The following day I called customer to make them aware of the payment and for them to reactivate my line, it was a struggle and it took a few calls and days for my number to start working but my phone was still blocked. On 16th I called to inform vodacom that my phone was still blocked and I was told it would take 72 hours to unblock the phone I waited until Thursday and still no luck. I went to the vodacom store and the gentleman who was assisting me said I would need to fill out a form because he tried to unblock the phone but did not succeed. While he was busy filling out the forms I was also on the line with customer care to find out why my phone was was still blacklisted, the lady I was on the phone with said my phone wouldn't be ok within 24 hours and the gentleman said his process would take 24 hours also. On Monday 23rd I went back to the vodacom store and the gentleman who helped me before was not at work so they gave me a phone to call customer care to find out what the problem was. The lady I spoke with said I must forward the forms I had filled out on Friday to her supervisor (***) and they would unblock my phone immediately because it was not the first time I had called for that issue, but still my phone remained blocked. This morning I again called customer care to find out why my phone was still not working, the lady I spoke to told me she had escalated the matter to her supervisor and the supervisor would call me back before end of business today and my phone would be fixed. My phone is still not working after almost 3 weeks. I have been calling and calling but I'm not getting any help and that is frustrating. I'm at a point where I I'm considering canceling my contract and moving my number to another phone network company because vodacom has really failed me, it feels as if I'm being punished for having financial challenges, yes I was owing but I settled my account but it seems as though vodacom doesn't care.
