Money paid by MiWay to an account and bank that do not belong to me

I am extremely dissapointed with MiWay for messing me around with my refund, I sent off my documents in January 21 and after numerous calls and emails I eventually got out Busisiwe Seth who I thought was great with her assistance and who confirmed everything will be sorted in April 2022. She apologised for the inconvenience and bad service from MiWay. Yesterday 10 May 2022 I called in again after numerous attempts before then to tell her that my issue was not resolved and when she told me but the payment was made on the 25 April 2022 I requested a proof of payment. When that came through eventually I discovered the bank details and the bank did not belong to me. So again, they investigating and I have to wait. My concern is who does that banking details belong to where the money was paid into….how did they get it so wrong after me sending them the relevant information numerous times….I am waiting on Busisiwe Seth to get back to me with this information. Let’s see if she calls today….The process is tiring, having to call them to check up then discovering that the money got paid into a different bank account. Now having to call in again for them to fix their mess. I guess this is the times we living in….MiWay team you got to do better….
