Vodacom data sim has poor connectivity , vodacom refuse to cancel contract within 14days return period

I ordered a data sim contract with vodacom on the 6th of February The sim was activated on the 11th of February. upon using I saw that the internet connectivity of the sim card was extremely poor. I need the data for calls made on microsoft teams but with this sim card, the teams calls disconnect frequently due to poor internet connection

Here is the funny part. I have a vodacom prepaid contract on which I load data and am able to connect with no internet connection issues.

Since the sim does not connect properly, I am still buying data on my prepaid and will be charged for a contract sim card that is effectively useless to me.

I tried cancelling the contract on the 15th January ( 1working day after delivery) but have been shunned from pillar to post. Eventually I was told that the cancellation has been logged ref: *** and someone will call me by Friday.

Today (17th January) I get an sms (after receiving no calls from vodacom), that the ticket has been resolved. I call again and am advised that they refuse to cancel my contract because the issue is the network in my area. Vodacom also debited my account for an some unknown reason way before my stipulated debit order date

how is the issue caused by the network in my area if I am using a vodacom prepaid sim that works fine? Vodacom is throttling their data sim contracts so you are actually paying more for less!

Vodacom, please will you cancel my contract and not charge me any cancellation costs as I am well within the 14 days cancellation period as per your own policy! Please also return the money you debited from my account as it does not even equal the contract fee therefore cannot be justified.

my next move will be to lay a complaint with Consumer complaints as well as consumer goods and services ombud !
