Vodacom incorrect contract billing

I signed a renewal of my Vodacom fiber contract on 2nd February, which was confirmed with the agent Bongiwe on 6th February for R599.00 per month. On 7th March I received an invoice for R1 277.47, (R698.47 more than my existing contract), for my fiber with a credit of R479.18 making R798.29 my payable amount instead of the contracted R599.00. I have been querying this with Vodacom on a daily basis since the 7th March. Amaaraa Wolhuter on 7th, 8th, 11th,13th & 14th March, with no response from the WhatsApp contact she sent me. And no answer to the phone calls. Sithembiso on 14th March who said he would call me at the close of business. No response Sinothando on 15th March who was escalating the matter and would get the line supervisor to call me that day, which I am still waiting for. I was given Jason Duko's email address....no response to any of my emails from 15th & 19th March either. On 16th March I contacted Vodacom's social media contact and the reply advised that the matter would be sent to the relevant team and I should give them time to respond. I followed up on 20th and was given the same reply. Butsha on 22nd March, who told me the person assigned to my ticket number from 7th March is not available and it has not been attended to yet. I demanded to speak to the line supervisor, which was obviously not possible, but she told he would call me today. They are very quick to sign up contracts and renewals but disgusting at correcting their own errors. And you can never speak to anyone with more than two brain cells who can assist, their only capability is to escalate. My concern is, next week is debit order day, and they will debit me that incorrect amount. I am a pensioner and do not have that extra money in my bank which I will NEVER get refunded.
