Furious Customer

I've called on the 13 September 2023 to renew my contract. On the 20 September 2023 I've called vodacom again to reduce the premium because I felt it was still to high. The person I've spoke to said he'll.send a request for the contract to be cancelled and it will take up to 72 hours. On the 27th I've called again to find out how fare they're with my cancellation, it still hasn't been processed. They've had 9 fays to do it before the new month, to date I'm still waiting!!!! I've received a sms to ask how the process went I've said in the sms response about my unhappiness and a lady called Matshidiso from Vodacom survey Department called me back and she said she'll follow it up. She did sent me a sms on the 06 October advising "Please be advised the upgrades department is still busy with your query, they will contact you to give feed back sooner." To date still nothing. I refuse to pay for that higher contract for the next 24 months. Could someone please call me back assp to resolve this issue. I was within my cool off period to cancel the contract. I don't understand how it can take you guys so long to resolve this??
