Rain - Inconvenience

I am extremely frustrated with Rain, currently there is no one taking calls at their offices, you are advised to use online support. They deduct on the 1st of every month, the funds in my account is sufficient but for some reason the debit did not go off, I tried loading a payment it keeps saying payment declined so I have been without internet service since the 02.09.2020, I cannot get a hold of of anyone & they are not responding to the Online Support Query. I had to purchase additional data, so that I could do "online support" but to no avail. I have contacted Rain before querying regarding debit orders as I get paid on the 15th. They only said you have to make sure you have money in your account. This is such an inconvenience. They are overcharging their customers I know for a fact that I do not use 3gig after hrs (18h00-23h00) it is like they estimate and that is not fair.
