Pathetic service

Vodacom service is so pathetic. I even regret taking a contract with them. My home router is not working since Saturday, I was told my data is depleted which to my surprise I did not understand how, but I loaded it anyway. It is now turning out that it is the SIM card that has a problem, I was requested to do a SIM swap and paid for it. It is still not working and no one knows what the problem is now. I called the call centre and they are telling me I should wait for 24 hrs to be called. I requested for them to cancel the contract since they are failing to deliver, they didn’t answer, and I called within operating hours! This is such an inconvenience!
