Incorrect upgrade!

What a disaster to upgrade a contract with Cell C. I upgraded my mobile data contract this morning only to find out after wasting more than 90 min speaking to multiple agents that they’ve upgraded me to a Home Connecta contract and not mobile data. Why on earth would I want to replace mobile data with fixed location data! I am told that it will take 3 days to sort out when it took minutes to upgrade me to a wrong product! Unacceptable, I expect to have it resolved today. Shocking service from a company that I have been loyal to for years!
