NO CUSTOMER SERVICE!!!

I contacted their support team online (which is the only platform that they do have) to rectify that I've been incorrectly billed on my account. They failed to call or sort the problem out timeously when I queried it. Their robotic emails sends a reply to your complaint after they've deducted the money from your account. You can never get through on the only mobile number they provide. They don't have anyone working in the office and say its due to lockdown, which by the way we are on Level 3 right now in this country and at least a third of the workforce is back at work. Makes me wonder if they even have real people working for them as all I ever received is email replies from Zendesk (a robot?) How does one communicate or relay a frustration as such to a robot? All I request is for my account to be rectified and updated.
