Bad credit record and payments not reflecting when paying via the builders credit app

I am now sick and tired of builders.

I have been struggling with builders from the beginning.

When I app**** for my builders store credit card instore I filled in and ticked the debit order tab on the application. But every month I have to go into the store and pay.

I have been using the builders credit app from the playstore for a few months now.

I have made my payments via the app, that in return sends me a otp via PayU, that was deducted from my account. But just went into my statement for the last two month's. But no payment is reflecting. I have sent an email to the payments@rcs account and sent a email to the debit order email account but noting is happening. Please sort out your ****.... And tell me where my money went that I payed.

I emailed rcs proof of the payments etc and more then two months and nothing.

This is a disgrace.
