Old Mutual does not acknowledge emails they request

Called in 2 weeks ago to confirm a cancelled policy. Apparently i spoke to a ghost because on following up , nothing was cancelled. So call in to 1 section, very quick all done. Next Department, asks for confirmation email, will get back to me next day. No problem sent Thursday 29th 2022 11am. Being in Tech field I also sent delivery request Its 2 January 2023. Nothing, no follow-up, fkin twilght zone they gonna debit my account , ruin my credit rating and any follow-up is going to be excuse filled, I'd bet the email got lost in cyberspace. Not holding my breath
