Vodacom online pathetic service

Last week Friday November 23,2018, I app**** for a Vodacom WIFI deal online, I was sent an email that a consultant will contact me in 24 hours, I called customer care on Saturday and was informed that they are back logged and will call me should I not get a call by Monday I should call them, I waited Monday and received no call, on Tuesday I tried the online department I waited 1 hour on the line and no response, On Tuesday 27 November 2018, I sent an email as there was no other way to contact the online department, I was asked to authenticate myself which I did, today I got a response from customer care telling me they have contacted the online department and was informed me the deal was no longer available and I can apply for another deal and that they will not be able to answer for the online department, I was put through the online department until the call got cut, how is it my problem the deal is no longer available, I app**** last Friday not today, common courtesy would have been to send an email, an sms a call or something, and I know for a fact that this has not only happened to me but to a few other people, Vodacom online has a very Sh**** way of dealing with contracts and new customers, the other people I know have spent hours holding the line and using the airtime to call Vodacom online, understandable it was a busy period but I don't think customers should be treated that way it is disgusting and very unprofessional for a service provider.
