Wish complaint: Cancelling my order for a refund

I had ordered some merchandise on December 28thh and when I received my total it was more then in thought it should be so I called to cancel my order and get a refund to my account. The rep that helped me cancelled my order and said he wad refunding my account for 64.88. When doing this he sent me a message about the refund and asked me to read it back to him in doing so he refunded me 164.88 and I told him this. He said that was a mistake and he said how can I get my 100.00 back from the money he refunded me. He spoke with his manager and they told me to go to the nearest CVS and get a 100.00 Google play card mind you this was 30 minutes away. So I took another 100.00 out of my account and bought the card. So I stayed on the phone with him that whole time he wouldn’t let me hang up thebphobe. I got the card gave him the numbers off the card and he asked me for the last 4 digits of my account and he comes back and said there was a server error. The message that he sent me saying 164.88 was credited to my account was erased out of my message I didn’t do it. But I got a message from Google saying my 100.00 was credited to my account but I haven’t heard anything from either of those refunds I have not got any credits to my account. But I go an email saying my order had shipped. I cancelled the order so howbwas it shipped. I would appreciate your help in this matter.
