Bill dispute

I'm starting to get annoying by Mr price service. Below I've attached my bank statement and October Mr Price statement stating that I didn't pay in May and sent it to *** for the second time and still he or she hasn't rep****.

On Sunday 28/11 Mr price consultant called and confirmed that my May payment of R450 was received. I'm failing to understand why in October statement have R430 missing payments for May. May I get my R430 back.

That guy promised to call me back regarding a credit of R430, today it's Thrusday and still no feedback, and I haven't received my money.

I'm sending this complaint for the last time now.
