****** of my ticket after a successful sale

Yesterday bought the Nedbank final ticket at 13:15 and the purchase was successful, but have not yet received the email confirming the sale nor the link to download the ticket. Been calling their call Centre since 15:00 yesterday 05/05/2025 and I cant be transferred to an agent due to high volume calls. Okay, I understood yesterday was quite a hectic day, but even today just minutes after 08:00 I still can't get through to an Agent for the same excuse. Computicket can do better than this. Their IT systems can handle such volumes since they have been around for quite sometime. This is disrespect to the people who support their business. If it was possible to give a zero rating that is what they would have got from me.
