Arrangements with vodacom a ****

I could not pay my account end of January. I received a call from a gentleman at vodacom and made an arrangement to pay on Friday 28th.This morning I spoke to vodacom who assured me the arrangement shows on both their systems and will not be cut. 5 minutes later my line was cut. I called now and spoke to Olletu at 8.37 am.who told me the arrangement only works if I made an immediate payment so they cut me even if I have an arrangement. As the arrangement dont count without payment. My details are Nadeema Buckton *** *** I have so many numbers with vodacom this is unacceptable
