PATHETIC SERVICE!!!!!

I upgraded my phone contract on the 22nd of October 2021. I decided I wanted a different phone, so on the 25th of October I called in and requested a different phone. I was told that they will process it and send the courier to pick the phone up. I received the phone that I had initially ordered, I haven't even opened the box. Every week I've been phoning Vodacom but till this day I have not received any assistance regarding this matter. It's almost a month now. The customer service is pathetic!!!! They are to quick to phone you but yet when you need help, no one can assist you!!!!
