Delaid response from VOX

On the 6th of June 2022, I had asked a friend to make a payment on my account, unfortunately she had used the wrong reference, immediately I had phoned in to explain the mistake, it was then told to me that they would allocate it immediately, mind you this was on the 6th, I had sent proof of payment through thinking that it would be sorted as discussed over the phone. It's the 20th of June 2022 now to wake up to a suspended account, I've emailed them explaining the problem, as I struggled all morning to get through to them. Ive now received a email of demand after I emailed them stating my problem, my problem is don't say that you would deal with it thinking that it was sorted only to find out that now they terminate my wifi now I have to pay extra fees so it can be switched on and they expect me to pay for "the month I skipped" which I did I sent them proof of payment. I need wifi to be able to do my job. This is frustrating me.
