poor customer service from vodacom

So I apply for a Huawei pocket router with a contract of data only on the on the 21/05/2026, which was approved. I send all the necessary documents as per their request. On Friday the 22 June the agent from Vodacom online calls me to make arrangements for the delivery of the router, I told her I won't be available at my work address as I am attending a workshop the following week. she said she will call me next week to arrange with the delivery. Another agent calls me to arrange for the delivery of the device on the week of the 1st June - 5th June. I have been waiting for the email from the courier as to when they will deliver the device, on Tuesday the 02 June I reach out to Vodacom online to find out what's happening with my order via email, I didn't get a response. on Friday the 5th I had to use my airtime to find out the status of delivery of the device, I was told Vodacom cancelled the contract without my consent, they claimed they called me and I didn't answer the phone, (which is not true) they didn't leave me an email, I had to find out that way, so I made another application on Friday now the online approvals are dragging their feet, I need the device before the 12 June as I am going on vacation outside the country. even after pleading with them that I need to leave the device with my son so we can be in contact, they don't seem to care. this service really falls below a South African standard, I am so disappointed.
