Bad service

I was contacted by a consultant at Elite mobile approximately 3months ago regarding a cell phone contract. When I advised them that we would like to review the device first before proceeding, they went along with things on their side. We made contact with them numorous times to advise that we don't want the device they were offering but instead are interested in another device. They went ahead and sent me the very device we advised that we DID NOT want! When trying to get them to collect it we waited over a month, yet they also continued to bill my account and deduct funds after we specifically told them we don't want this device. The unwanted device was finally collected 17/09/2020. We have since been calling to find out when we will be refunded what is owed to us. We were advised last weekend Saturday that the refund was processed and that the funds will be in my account within 24hrs. When my Fiancé phoned them the next day, to our disgust we found out that nothing has been done. After phoning and phoning with no assistance my Fiancés number was blocked by vodacoms call center. I am disgusted to say that I phoned to follow up again today and when I was explaining the situation to the consultant he put the phone down in my ear. Vodacom is quick to take money out of your account but when it comes to paying their "clients" back what is due to them, they don't want to pay!
