I settled the amount that I was owing on my account on the 24th of January and sent them the proof of payment on the same day. I followed up with them on the 27th since my services were also affected. They then stated that the payment is reflecting on the debtors account but it will take them 7 to 14 days to allocate my payment and resume my services. This is highly unfair as I have to buy data now to sustain me even though I had settled my account. Which company takes 14 days to allocate a payment? On top of that, their agents don't respond to what's app and emails. I am really considering cancelling my contract with them and moving to another network provider with better customer service
