Billing Issue caused me to lose hours of work and impeded on ability to work

I have been with rsaweb for a while now and i even brought some friend and acquaintances into the fold I noticed a billing issue on my account and contacted the account team to sort it you. I was asked to provide proof of payment (which was a first) and i did, i was then told that the payment was going to be allocated to my account and my service will stay active until then and after an hour i received an email confirming that the payment had been allocated to my account but then things took an unexpected turn. My internet got suspended and i lost half day worth of work. i had to find a way to reach out again to the rsaweb team to get it unsuspended then the next day, i followed up by asking how and why this happened, i got an agent called Amahle and essentially i was told that it was my fault, that i took too long to provide a proof of payment (said payment was reflecting on my account statement until it somehow disappeared) and although my account is due and is payable on the first, well the system suspended it on the 26th cos they bill customer in advance. like how a service can be suspended before the payment date, i'm still trying to square that circle I am not sure i will keep recommending people in my circle to switch to rsaweb
