WebAfrica overcharging - check your account

Since March 2023 I've been overcharged by almost R250 p.m. for a service I didn't request and also didn't receive. I was contacted via an SMS stating that my fibre line will be upgraded for free, I made nothing of it as I saw no difference in my speed. This month upon inspecting my debit orders I realised that I am paying more for my line than the top tier line they have on offer, while my service sits three Tiers down.
