Frustrated Customer

I've made payments for both April and May 2025 and to my surprise they haven't been allocated. I've been followingup and been told all the excuses in the world, been escalated from one department to another with this issue unresolved instead I'm being told about a policy of 7 to 14 days which has long passed. I have also provided proof of payments for the months inquiry. That time I'm calling with my own airtime, I hold long on the call for assistance just to get the same feedback that finance is busy with it. What is this? Yall are very quick to let your debt department to call me and also ruining my credit profile. I need this sorted out ASAP as I have done my part and put in effort by consistently following up only to get no assistance. Even your team leaders are never available to assist. I don't expect such a huge business like Makro to have an *********** staff. What is customer service for?
