Very disappointing customer service, 2nd time round

I've been trying to cancel a contract for the past 2 weeks. Received a quote, agent at the branch sais no need to sign the quote, just pay the amount, call customer service and within 3 hours you will receive a confirmation sms. Stil waiting, I call and spoke to a few agents, I have Ref no's, names, but now received an sms, again after I've called them, with a name in who will be helping me, but only 8.1.2025. The one has no clue as to your rules, terms and processes. Likes to blame each other and pass thr buck. I need my contract cancelled today, because I have followed the process, explained by customer services. deverything
