Vodacom service is the worst evert

There was ***** committed on my name 2019. First I saw I paid more than what I was support to. When I phone Vodacom the first time they told me I made a migration and a sim swap on on one of my contracts. I told them I asked at Vodacom Vaalmall to cancel the number because the contract expired. Witch never happen. After that there was a R12000 deducted from my account and I phone Vodacom again and used them about Whats happening because I didn't even get my invoices as per email before. Then they told me and said I phoned in to change my email and asked for a migration. Witch I didn't. Then after I asked for the voice-notes and submitted all the paperwork as requite by vodacom. There after they said there is not enough info I must pay the money. How must i pay If I did not do it? Still after 2 years vodacom handed me over to the Lawyers. There I phoned the Lawyers and re submit all the email, voice-notes and screenshots to them and still there is nothing happening. I want to buy a house no I cant because of this nonsense. Who can help me because vodacom cant?
