Customer service and resolutions takes months - seriously!

I upgraded my fibre line to a 100 meg line around June 2020 - this was apparently done, however upon doing tests on a regular bases i never received the line that i was paying for. i started querying and got endless run around, why am i still paying for a 100 meg line, and why does it take so long to downgrade my line. i eventually cancelled my line as a result of moving house (and i need to get a new contract for new house that does not have fibre - hmmm vodacom or no vodacom) How many emails, telephone calls does it take to get this resolved. Vodacom is so quick to cancel a line yet it has taken months to resolve my issue on the 100 meg line and almost a month to downgrade the line back to a 20 Meg line. what is so difficult to get this resolved? How many times does one have to phone to keep on escalating this?

Here are a list of what is STILL outstanding : * Backdated refund wanted on line never received - check usage and proof supp**** * proof of usage wanted for last few months - to assess how much i need for new place * new solution required on new property - and please no ridiculous rates
