Terribly unreasonable and inconsiderate!

I moved from Durbanville in November. I gave specific instructions to put a point upstairs at the window, on arrival the point was not at the window but next to the bed. I did not plan on working from bed. They then told me I had to pay for them to come back and move the point as these instructions were not clear, but they were, I had all on a whatsapp conversation which I shared time and time again with them. I still had to pay. Now, they have cut my line since yesterday morning. I have explained I am working on a deadline which is a 40K job, we are likely to lose this Client. My daughter is a teenager and does online home school. I was wrong as I was not aware payments were behind, my last statement said I owed R1400.00, I used the very last cash in my account and paid this. Then they tell me that it won't be switched on until it reflects and that POP's are not good enough. Then, they tell me I owe another R1300!!!! Because I was desperate I paid it and asked for a justification of this massive arrears amount! Which I'm still waiting for, I also paid this as an immediate transfer so it reflects immediately! Nothing, all I get is we follow a ticket system. I started by asking them so nicely and then I got rude, which I hate getting but they've really put me in a tight spot here! And they honestly do not care at all about my situation, I PAID, Have sent Proof! Not enough! They then say the amounts were April, May, June outstanding! But I sent them Proof of payments for those months too!!!!! *** is all I can say and I will NEVER recommend this firm to anyone! Nothing but bad service and uncaring staff! I have spent R400 on data these last two days just to try get some work and schooling done! Plus the R2000 odd I paid to get reactivated!
