Jenny internet poor customer relationships

I paid this month for my internet just to have my internet switched off half way through the month without any warning. After multiple phone calls i was told I missed a payment 4 months ago, i told jenny support that I was not aware and I will pay it in full end of the month as it was my oversight. The answer was simply no and they switched off my internet for an oversight several months ago even after paying this month. Multiple colleges of mine is unhappy with support and quality from jenny.
