Nightmare dealing with Webafrica and suggest anyone stay away from this ISP

Nightmare dealing with Webafrica and suggest anyone stay away from this ISP. Their communication is poor, they restrict you to use their WhatsApp facility with poorly trained staff. You sit and wait whole days and overlapping days for a response, then transferred from agent to agent. they billed me extra for 3 months for an upgrade available on their online portal. Upgrade was processed administratively and new billing amount was invoiced but no physical upgrade was done. I queried this for months& then they apologised for not doing the upgrade and I was advised they do not have the available speed and I must contact accounts for the refunds. Accounts never refunded months later. I am trying to cancel this poor service for 3 days and get placed on hold for entire days and passed from agent to agent. Will just stop my debit order as there is no other recourse as telephonic support is non-existent and I am also passed from team to team via their limited telephone support. Steer clear of WebAfrica if you expect hassle-free services which are rather antagonising me.
