Old Mutual has cost me big time

i have visited Old Mutual Diepkloof Branch and i have been assisted by the lady name Thandeka, all i needed is to activate my money app and transfer money. i have speeded 2 hours when she was trying to assist me. she tried calling for assistance and they told us that is my service provider problem, while i could receive sms from other service providers, second option is my phone which im currently using A52. i need asked them which phone should one get that compatible to use Old Mutual app? they didn't have an answer. how could one be able to get his money since the app is not working, internet banking is not working and cell phone banking is not working . is sad a brand like Old Mutual cant assist me and really needed to send that money. i dont think they know of some called opportunity cost . i could not settle a del because of Old Mutual.
