Call for a better service and Improve customer experience

Here's a possible way to summarize the situation to a third party:

"Hi, I wanted to share with you a frustrating experience I had with RCS, the company that manages my Pick n Pay store account. I went to the store to buy groceries, but my card was damaged and I couldn't use it. The store staff were helpful and replaced my card, but when I tried to contact RCS to resolve the issue, I was repeatedly disconnected and ignored.

I'm really disappointed in the service I received, especially since I've always made my payments on time. I've written to them to express my frustration and to ask them to assist me in setting up my new card. I'm hoping they'll take my complaint seriously and improve their customer service."
