Terrible service

Truth about momentum is that they are failing, 3 weeks back, I called to tell them my multiply money card has expired, was advised to order a new one at a fee of R100, few days later, received a call that product is discontinued, called them, was told I will receive a refund of fee, called last week again was told same thing, till today no refund . Last month I bought Nandos voucher through app, did receive them,got them after I complained. Sunday bought Nando’s voucher still not received.
