I feel ****med by RCS

I opened a game credit card in 2022, I bought a washing machine I paid and in 2023 I took a phone for my daughter I continued paying I have never been a bad customer who missed payment, in September 2023 I made payment via EFT I made a mistake and used my cell number as a reference end of September they called and said I'm owing I must send proof of payment i did. In October they called and said I'm owing I said but I did send proof of payment only then they told me you send the wrong proof we don't accept screen shorts I went to the bank and asked for proof I send to them they said it's wrong the then send me an example of proof to send I did and in few days the money was updated. On the 24th of November 2023 I paid for October to December I used the correct reference this time. Around the 28 I received a call thar my account is in areas, I said but I paid on the 24th they said it's okay maybe it will reflect soon on the 7th of December I received a call your account is in areas, but I paid send proof to collection I did few days my proof was acknowledged by email they said they will send it to the finance department. I relaxed on the 20 another call same conversation same actions. On the 8th of January 2024 I called them and asked what is going on why am I not seeing the money on the statement they asked me who did I send proof to and when I counted for them and they change the story now and said the one I send on the 20th I will reflect on the 10th of Jan it takes 7 to 14 days on the 10th I received and email saying they have received my proof of payment that's I send on the 8th it will be send to the relevant department and I get charged for all the calls and email I receive I'm sure I was charged for the call I made myself for collections I have been charged more than 500 including interests I feel ****ed and ****** by RCS today is the 15th I just received a call again I was told my account s in areas I told the lady the Same thing I have been saying since last year November till today after I have sent the same pop many times My account is still in areas
