Pick n Pay Sedgefield treating the elderly badly

I am so sick and tired of Pick n Pay Sedgefield treating my elderly mother like dirt!! She tries to withdraw money from her Tymebank account and they refuse to provide her the service. When she calls them on ***, they hang up the call when she tries to speak to them and when she calls back, the don't answer. I think I should contact Tymebank head office to ask them why they provide a company that does this to old people a license to operate their services!!!
