*****ing money from customers

I have 2 data contracts that came with free routers free of charge as a special 6 years back when I took out contracts. I lost track of both and Vodacom started billing me for these data contracts after 2 years without me picking it up. On the 17th of May 2021 at 16h10 I went to the Vodacom shop in Highveld mall Witbank and spoke to Nomfundo who told me she cancelled both and I should wait till the 1st of July to verify the contracts being stopped. Both contracts still went off from my bank. On the 10th of July at 09h15 I spoke to Given at the customer care center (082135) who told me both contracts are still active. She told me she cancelled both and she is sorry for the inconvenience caused. On the 27th of July at 09h40 I spoke to Nosipho at the call center (082135) who confirmed the cancellation of both contracts and gave me a reference number: ***. This morning on the 2nd of August both contracts still went off from my bank!
