Two months of battling with you just to get my claim processed

It's been two months now that I am struggling with you to get my claim processed. Every time you come back with some kind of excuse. I've send emails to all the email addresses provided to me and I'm not getting feedback. I'm tired of hearing your systems are offline. It's costing me data, airtime and time. My payment was processed but it was rejected because my banking details were not updated (just my surname that was incorrect) I changed it that same day but yet to receive a reply. After telling your agent I haven't received my new ID to change my surname, I got a response with only "I made myself clear" - What the hell? I've been working 18 years, and now that I can claim, this is how you treat us. I want my money!
