Can Vodacom acknowledge and rectify there mistakes

Since February 2021 till today I have been receiving terrible service from Vodacom. First it was my monthly discount which was removed, then I was given a faulty device which was in repairs the whole of 2021. There were services added to my account which I did not request. The Vodacom coverage in my area where I stay is poor. The device listed on the insurance was not even the device which was on my contract. Incorrect debit order amounts. I still have not received my new device since January 2022. They even took my vodabucks due to a system error and it has not been credited back to my account. Today I find that I have been listed on ITC for an unpaid account of more than R1600 while my account is paid up to date and my bill for end of February is only R175 because Vodacom owes me a credit as they deducted the incorrect amount from my account in January. I am at breaking point with this account.
