Momentum multiply -shocking service

Have a few issues with Momentum Multiply. Cannot seem to get breakdown of my points accrued. Sent email to Julie Govender and Fourie Botha. They do not respond to my emails. Also tried to phone call centre today. Cannot get through!! So disappointed with staff I have been dealing with. I am not sure what they are trying to hide. Asked so many times to ph me but they ignore my requests. Is there nobody in a managerial capacity who is willing to deal with the customer's requests!
