My Money or they take their fridge

This mail refers to the fridge purchased at Lewis stores, Estcourt Branch. I made an arrangement to pay out the fridge in three months with the manager. However everytime I went to pay the slip showed a different amount. Manager was informed but she assured me that its how the system works, thus I should ignore and continue with the three months arrangement. The last transfer was done over the bank which the manager told me to pay the amount on the system and I will be reimbursed. The transfer was to be done over 3 days, surprisingly it went on until a full month with no transfer. I called them over and over and they told me they still waiting for authorization. But now surprisingly after a full month of waiting they tell me my money wont be transferred I should contact the manager who is now suspended. How I am to contact a suspended person that I don't even have her personal number? My question now is that why did they take a full month to tell me this. I've been calling and wasting my money in vain. They should have stated that they don't do the three months payment at first, I want my R3902 back or they should take the fridge . I sent an email to their customer care.
