Vodacom ********* Business practices!

This is the 2nd time now, i contact them they pass me over to another branch and no contact. Im a working person and only have so many days free and vodacom even thou i have contacted them to say which days i am free and even called them on my free days never get back to me on that day then want to call days later when im working. They are now charging me for an extra month because they didnt cancel a service that i asked them to cancel 2 months ago. Vodacom is very *********, never buy with vodacom they will delay your cancellation processes so they can keep charging you even if you contact them waay in advance. Ive wasted airtime constantly trying to contact them on my free days I just then get passed over to someone else who then doesnt contact me back they then call me when im busy and want to use the excuse its then my fault because they tried to call and they just then cancel the whole process and i have to start all over again im very frustrated. Im considering taking further action because this is 100% ******* from vodacom when you give more than a months notice and they dont cancel and then still want to charge you.
