Contract Cancellation

I am a customer of Vodacom since 1999 and still using the same cellphone number. In July 2019 I lost my daughter & immediately cancelled the contract of her cellphone bt to my surprise in June 2020 a debit was still deducting & I phoned your company to claim a refund but that never happened. My son lost his cellphone in 2022, reported it immediately but till today a sum of R286.99 is still deducted from my account, worse there is an amount of R65.22 from my account a 1 Gig data bt NO one is receiving it as there is no one with the cell number they have registered. I am the main contractor bt my cellphone does not appear in your system. I am really not happy with the treatment I get from this company. I asked for a refund and the lady who was assisting me said she wl register it bt I know 'no one wl ever bother to attend to my complaint, this company does not care about it's clientele
