This company gave an IT company by the name of Altron nupay that deals with debit orders, to debit my fnb account for the amount of R112x2 which is a total of R224.i have no business dealings with the said company and have never signed a contract with them,when i want my refund they tell me they do not refund and i should not threaten them after i said i will publish this everywhere.I need help. As an unemployed person this is a lot of money.they further have blocked my bank from reversing the payments
