Data switching

I'm very disappointed of the service that mtn consultants have given me, I've been accumulating loyalty points since it was introduced. I had 8900 points and I received a message stating that certain points for 3 years will be taken away if not spend I lost points, so on the 17-10-2020 I decided to spend them because they took another 2000 something points I had 5000 something points remaining. I used them to buy data which was loyalty ayoba data worth 2500 points I can't use them because I'm told I must download their ayoba app to use them, I don't want that I want data that I can use on internet they can't help to switch the unused data.At vodacom if you have such points they offer u a smart phone or voucher to spend at certain retail store with mtn you have to use them on the same products, is not encouraging me to keep buying products and earn points to spend on same products, I spoke to Jessica the team leader to assist to switch those data to datas I can use for internet but she only apologized for my loss really I mean the data is not used why can't I be assisted because I was not looking forward to spend my points, she told me that my feedback I've raised will be considered but it will be late for me. As a company you should have innovative ideas to keep your clients happy for using your products you should think of competitors out there of how they keep and attract customers to use their products.
