Fibre sky link unprofessional and unreliable service

Fibre sky link suspended my connection today of all days even though I paid for the subscription in full long before the end of November how pathetic. What’s the use of a unique reference if a payment still cannot be allocated to my account. Now I must wait for Monday to connect to the internet that’s if they won’t be demanding more money for their ****ty service. Honestly is there no accounts department??? I paid over a week ago such bull****. I can’t wait to cancel this **** service
