Incorrect upgrade from Mobile DATA SIM to Home DATA SIMme D

Upgraded my 2nd data only line mid June 2024. The consultant who is the one called me for the upgrade confirmed it was mobile router I was to receive. On receipt it was a home router. I didn't mind since I afford the cost, I kept my SIM on the old device. Went to holiday in KZN (uMkhomazi area), there is no Vodacom coverage - just mentioning. I came back 12 July 2024 my data SIM was still working. It stopped on Sunday 14 July 2024. Last Saturday 20 July 2024 I visited the nearest shop Kempton park Festival Mall. The guy told me that Vodacom online agents are ***********, some with 2 weeks experience. I should never buy online ever again. He gave me a number to call after sales service. The lady there stated the dispute is going to be difficult since it is now over 14 days. I am now awaiting the outcome in the next 3 - 7 days. All I need is for this SIM to operate on a mobile device. Why grounded at home. I'm frustrated right now and disappointed with Vodacom - being a client for +15 years.
