Disgusting Service

I took a wardrobe on an online layby from this company i think from July and have been paying each month ever since with last payment being R500 on the 17th of December and this payment was made using their online payment platform. I emailed them numerous times to advise i gave paid up my layby and would like to arrange delivery for my item but i kept being told that my payment is not reflecting regardless of me sending the proof of payment more than 5 times then they tell me the finance department is closed and i should get feedback in Jan but still nothing from them and at this point i am fed up to be honest, i just want all my money back as i cannot deal with such nonsense from such a big known company. I have delt with a Mbali Banda from their complaints department but she's been quiet since December. Nobody has taken the time to help resolve my query and i am so disgusted with their service hence i want nothing to do with them anymore i just want my full refund and i will go where customers are valued.
