Hearing Aids costly surprises

Archer & Mann Oudioloe in Wilgers,Pretoria is the agent for Widex Hearing aids producst.After spending R16000,00 plus the guarantee was valid until August 2020. The right side hearing aid went dead and I was quoted R4560.00 to replace it.No formal offer to assist me with the costs.Absolute shame the pensioners get ripped of like this
