Unfairly treated.

On March 3 2025 I made 2 payments via a link that is provided by Edgars/RCS,I have sent RCS and Edgars proof of payment on the 10th March as they requested via email and via their WhatsApp number up until today 23 April 2025 they are unable to track the payment,after numerous calls and mails they RCS is charging me for calls they make to me to try and resolve this,I feel unfairly treated as I used a link they provided me to make a supposedly easy way to make payments,I was advise that they use a 3rd party company for those payments and RCS is waiting for them to confirm if the payments was received.
