Vodacom data theft

Good day

I am 73 and I have been with Vodacom since the outset of my cellphone use.

I am terribly disappointed they don't allow email queries and their App is slow and unhelpful. No one gets back to you.

I took out a second contract 2 months ago and last night I checked I still had over 10 gigs of data left to use only to wake up and find I only had less than 400 megs left when I did not use any of it.

This is highway *******.

I am a disabled pensioner and I rely on being able to use my emails for query's to my medical aid and to contact my family on WhatsApp and Skype if I need help

Now Vodacom is ripping me off and I am very disappointed.

Isn't pensioners money even sacred or protected anymore.

What is this world commingled to?

At no stage was I informed the data would expire.

No help or response from Vodacom

At my Witts end
