Delayed cancellations

I called a week ago about a cancellation & kept doing a follow up since then & still no progress with the cancellation I've made & required a letter for Vodacom in Midrand to proceed with the sim swap and apparently you are bad news so please for the hundredth time remove my number from your system. The number in question is ********** 133 & my current contact number ********** 109. I never wanted anything to do with you & never have.
