Vodacom - very unhappy

Dear vodacom...

I am 1 very unhappy customer. I did a online upgrade for a Sony Xperia 10 on 3 June 2019 received the phone 4 June 2019. On the 10th July the phone started making nonsense. Took the phone in to a vodacom store on the 13th July. Got the phone back today 01 August, they replaced the phone with a new one but now the phone dont have any signal, i cant do anything with it, called vodacom and they said that we need to sync the phone (whatever that means). After speaking to vodacom still the phone doesnt pick up any signal so.... i am now demanding that someone contact me who can provide me with a solution to my problem. I dont want to speak to a consultant i want someone higher that can actually help me and i want this before 13:00 tomorrow 02 August. If i dont receive a response from you i will go to the branch drop the phone off and whatever you guys do with it then is your problem. I will tell the branch to cancel the contract aswell as all my other 4 contracts that i have with vodacom. I WILL NOT pay you a sent end of the month if this does not get sorted out!!! I want a new and different brand phone. This damn phone is not even 3 months old, not even 2 months old when it started giving me problems.

You can inbox me for my contact number. I expect to hear from you very soon and if i dont then you wont hear the end of me.
