Multiply customer care is shocking.

I received a monthly R125 reward voucher last Tues, the expiry date was 30 October. On Friday, 20 Oct, I checked, it was still there with 2 x R25 vouchers that I received. Today I check to redeem to it and it has disappeared. I try to query this with the wonderful whattapp service and I chat to someone describing 3 times what the problem was, she then sends me a screenshot of my account and states that there are no R125 vouchers. This was my query from the beginning, she/he just repeated what I am trying to query. What type of uneducated people working the whatsapp service. I hardly message on Whatsapp because of this. They are useless. Getting back to my query, this is the 4th time this year where I have tried to redeem vouchers before they expire only to find that they have disappeared. I also see that there seems to be problem with profile is not picking up my steps for the week. I also see my balance on my multiply money account is sometimes less than the last time I checked. I spoke to someone in Aug who said they will send me my statements which I do not receive, I am still waiting as my balance is still decreasing occasionally. Can someone who actually knows how to help me, please assist me.
