Terrible service to loyal customer

On the 25th of April I cashed in 1 x R200 and it failed on Momos side and I tried again with 1x R200 which also failed but when I went into my banking app, R400 was deducted but not reflecting in my Momo account.

I contacted the call center and.the gentlemen advised me that they have been experiencing problems with cashins and should wait 48 hours for funds to reflect.

On the 28th of April I contacted them several times and each time receiving a different reference number.

Till today, 2 May no one feom MTN has contacted me, and I don't mean robot emails, I mean, picked up the phone to apologise and rectify, but they have been making me feel as if Im lying, asking for the utmost ridiculous proof of payments when they can clearly see on my bank statements vs my momo app that it does not match.

It's poor service, I transacted R10k +- and this will be the last! i want my money back
