RCS damaging brands like Coricraft for pathetic admin

I have been asking maself countless times how businesses like Coricraft can affiliate themselves with such a pathetic brand. I have been utterly shattered from the time I purchased my expensive furniture item to absolutely disgust over their partnership with RCS. I called on the 18th Dec requesting that they amend my payment plan for the debit order as this was not confirmed in store by the "new manager" Coricraft Tygervalley. Agent Asisipho confirmed Arshad manager in the accounts department said its fine they have amended as requested to 24 months and it would take 48hrs. On the 24th a banging R1300 odd was deducted. Mind you I received my item on the 21st with delivery fee on the invoice excluded. I was so upset, I was just disgusted, disspointed and honestly so angry at all the pathetic admin of Coricraft accounts they have been. I am so regretful, I just want nothing to do with this account anymore affiliated with RCS, utter disgust. I need urgent attention on this matter, not ****** wasting my time anymore but m so unhappy honestly.
