Poor Support

I have had no problem with the network however the support on their website has issues. My account is currently in arrears and I need to urgently rectify the problem, When I press pay now nothing happens, when I go to support and try leaving a message it asks for our address yet will not accept the address, I then try everything, taking the commas away and writing street in full hoping that will work but still nothing. There isn't an email address or telephone number, I have tried to send a message via Instagram but no response!!! This is highly frustrating especially in these times when businesses like ours have been so badly affected by the pandemic and are trying to start a new businesses!!!
