Unreliable poor service

Received an emailed that I had missed a payment after activation in the same month. Emailed the accounts team to inform them a payment was made included the proof of payment, phoned the call centre line rings them gets muted and dropped. Email them again requesting for a callback with my contact details on the email. Phone again hoping to get assistance, automated voice messages apologises that they cannot take my phone call right now, no option to request a call back at all. A day later I receive a text that due to my termination of the account I will now have to pay R845 get home my WIFi has been disconnected!! Disappointing to say the least
