Contract upgrade paid up account and then you get blocked

We upgraded on 27.06.2025 Im am highly disappointed with telkoms billing team as our bill is only due end of July but they blocked our accounts. Im working from home, my husband is a site manager and he cant even open a gate. Guys this is 2025 not 1990 please come on get to the party switch eveyones phones and wifi back on because that is your fault on your side.

Or i will cancel my contract and know atleast why.
