Bad service

Good day

I have a contract with Vodacom since 2017 and after June 2019 when my account was due for upgrade I receive an invoice and showing that I have taken a Huawei router and a phone then the started debiting my account, of which I did not take, they are debiting me R95.51 and R230.00. Then I reported it to Vodacom and they promised my problem will be resolved. And they say I must go and do an affidavit at the police station and submit it together with my id copy but that never helped, even now I still having the problem. This is very bad customer service. Then in December 2019 I receive an invoice and said I must pay R666.61. I'm really need your help as this is still continuing in 2020.

Regards,
