Router not replaceable in 2 weeks

My router has been problematic for 2 weeks, so internet is intermittent. Infrastructure Provider came out within a day, replaced ONT, which we knew was not an issue (router is) and still the issue persists.

I have to follow-up with Afrihost on the new router and the only response is that they are waiting to hear back from the warehouse.

Despite informing Afrihost that if my issue remains unresolved, I would cancel, to date, there is no change. Upon cancelation, I am being told that the cancelation will only take effect 30 June and I need to arrange router return.

Am I supposed to pay for another month of intermittent internet? Will I be reimbursed for half a month of internet in May? Will the data I had to purchase due to lack of internet be reimbursed?

Truly the worst customer service when it comes to router issues and 0 escalation, even when requested.
