Walmart Rewards Mastercard Credit Card Reviews

Walmart is a terrible company to hold a credit card with! Terrible customer service which ends most of the time with unresolved issues, or drops calls!
I've called dozens of times to resolve issues, still not resolved, and on my most recent call, after 27minutes of time to dispute transactions AGAIN, the call went silent, as if put on hold, as the call was still showing connected, but no one returned to the call. After 10 minutes the call went to their survey and my issues again were left unresolved.
I actually found out during the call that I was refunded one of my disputed charges from a company months ago, yet not reversed and given back my interest from Walmart for this disputed charge, totalling $26 in interest.
I asked why it had not been credited back to me and they replied " it had not been applied to date". I asked for it to be applied, given they had already 3 months to do this, and she said she'd credit me $20 in interest and apply the $6 and change to my Rewards Balance! After telling her no, and asking why I would not want all my interest back, for a charge I never agreed to, just $20 of my interest charged back and $6 I would HAVE to spend in my REWARDS BALANCE where she would apply it, she could not answer why and told me ok she would put reverse all the interest, my call went silent. Unresolved AGAIN...like every call I make.
Their online site gives you minimal information...not ALL the information YOU should have.
They charge ridiculous interest!
To make a payment, it is not easy... and even when paying at their store, with cash, it took my payment 5 days to be applied to my card, when it should have been that same day, as I am informed it should take!
They are wrecking my credit, while It is not responsible, but THEM, for not dealing with disputed purchases, not reversing interest and fees when they should, and NOT treating their customers fairly, and in line with their contract details!
We need to get together and find a legal group to fight this! Why are we paying these high-interest rates, dealing with their issues, and having our credit hurt, when they ARE NOT ABIDING BY THEIR CONTRACT RESPONSIBILITIES?!
In addition, customer representatives fail to give you their names most of the time. The last one said they were forwarding me to ANOTHER department, even though she was the department I needed, and when I asked for her name, she hung up the call on me.
