Having syncing issues with Huawei device and VERY delayed responses to Weekly and Monthly Wins

Good day

This is now the fifth or sixth time I have had to follow up on requesting weekly and monthly wins that we aren't receiving. Since September last year we have had issues. Multiply informed us that they know of the problem and will correct it. Fast forward two months, we were still having issues. There were no correspondence sent to me regarding that the Huawei device should be re-linked, but accidently I saw the option in November and re-linked the device. All of the required Active and Recharge Dayz have been completed, not a single one was left out. I sent through the proof of all of the active days (via the Huawei Health App, as all of the steps are on there) and we only received 6 out of 11 vouchers and missed out on a crucial Monthly win (worth R115 on its own). Fast forward another month (December and January), my wife's account hasn't received her Weekly+Recharge+Monthly win for last week in December (3 vouchers) and the first week in January (2 vouchers; Weekly win and Recharge/boosted).

At this rate I need to keep an Excel sheet for all the vouchers that Multiply is owing and maybe charge interest for the amounts.

4xWeekly wins (3xR40 + 1xR60) 4xRecharge days/Boosted wins (3xR40 + 1xR60) 2xMonthly wins (2xR115)

Total: R590
