Terrible service and puts client's employment in jeopardy

A consultant from Vodacom phoned me and advised me that I am due for an upgrade on my account, would I like to go ahead on 12/10/2021. 14/10/2021 my devices were delivered. On 18/10/2021 I received a quote stating different monthly payments than was greed to with the consultant. The request to collect the devices was done the same day. After numerous e-mails and constant frustrating phone calls where I was advised that it was the courier companies responsibility to contact me for the collection the return parcel was collected on 28/10/2021.

On 29/10/2021 I was again contacted by the courier company to collect the parcel and had to advise them it was collected the previous day. After this I had to phone the after care line every day to follow up on the upgrade cancellation and every day I was told as soon as the devices have been booked in my upgrade will be reversed.

Today 03/11/2021 when I again followed up on the upgrade reversal progress I was told that after the devices was returned I should have phoned in to cancel. This process was not explained to me and why am I advised of this if I have contacted Vodacom nearly every day to follow up on this. After holding on to process the cancellation of the upgrade I was cut off. After several attempts to get back to the consultant that was assisting me and would phone me back my phone shows no service. After this all devices linked to my profile is inactive and I am not able to make or receive any calls. This is a device I use for business and not able to be reached may result in putting my employment at jeopardy. After being a loyal customer since 1995 with the same number. This is not treating your customers fairly and with due care.

If you are not able to receive or make calls how is the consultant able to confirm all is in order or how are you able to follow up if this is the only means of communication?
