My email address ***, bad customer service

On the 29nov2020 at 00h15 I bought a ponytail from wish.com immediately within 5 minutes I cancelled my order, wish.com promised me that they've refunded the money into my account but it will appear after 14 working days, if no so I must go to my bank will sort it out, on the 3rd December 2020, I went to the branch in Alex Mall Old mutual, I filled in dispute form for money reversal, my money was pending on my account even on my bank statement is not showing the transaction, I waited & waited, I've been going to the branch, calling old mutual money account department, sending emails no one seems interested to escalate my query, the amount is R2100, some of the staff members hung up on me, sometimes when I'm at the branch the tell me they are offline, emails will ask me questions but they are doing nothing to fix this & reverse my money to my account,the customer service is horrible this is absurd.
