Irate client due to no communication from Webafrica

I was with Webafrica for a few years and cancelled on the WhatsApp portal in 04 2024 and returned the Router to the Midrand depot. I have recently noticed I'm still being billed for a service I don't have anymore and am not using. I have for the last 3 weeks being trying to sort this issue out with banks and webafrica to no avail. The call center only has 2 options to choose from and have been unresolved as of yet. I have numerous ref # for calls on the WhatsApp portal in the last 3 weeks but always get dropped when it needs to be escalated to the Premium department. The is no option on the portal to speak to accounts, legal or cancellations departments. Webafrica are very quick to take your money but inept to resolve issues. I've requested multiple times to show me my usage to prove it's been cancelled but still am waiting for a response. I've on multiple occasions given them my new email address to correspond to me but as of yet nothing. I'm past being upset and demand compensation as well as answers. Not even worth a star rating pity I had to put one on to write this review.... WebAfrica legal or accounts department i challenge you to get back to me on a non WhatsApp portal or Spam phone line, smart phone drop spam calls.
