Bad customer service

I sent the first email on the 20th of May to Nkanyezi, I didn’t take the guy’s name the one I spoke to on the 25th coz I had sent another email on the 24th after I received an email from them on the 24th saying thank you for updating your details because I wanted to cancel an investment account with them, the guy told me I will have the funds on my account by Tuesday but that didn’t happen and I called again and spoke to Khensani who said my claim was submitted on the 25th and it takes 5 working days for the money to reflect on my account so the system shows that I will receive it yesterday and she has escalated the matter to the relevant department and her supervisor so I will have the funds yesterday but still nothing is showing
