Bad Service - Fibre Connection

I have been experiencing Intermittent internet connection on my fixed fibre line. log a service ticket #918947 - I have no internet Access with Accelerit and that is where it all started. i was give a standard feedback, "We have updated you modem firmware and moved you to a different channel" This continued to happen and as i complained and escalated i was told my line speed needs to be upgraded to a bigger package. I gate them a go ahead to upgrade the line. they were quick to generate an invoice which i immediately paid while i was on the line with the consultant. She told me that after 20 minutes i should restart my cpe and router and i will ready to to go. a day went and nothing happened. i called to check on what the issue was and i was told the VUMATEL have not done configurations, they spoke to their account manager and it will be done in the evening. next day morning i still did not have an upgraded line .i called again and spoke to one of the managers and i was told that i will receive a call back with an update. the whole day went again with a call from the manager. What i received was an online ticket update to say in am driving. This worsen this as at the time i was home nursing my injured right foot. I called again and spoke to senior manager who was mis informed by his own staff and to this hour i am waiting for a resolution. I thought it is important that i let them know why their business will not be sustainable if this this a type of service they give to their clients. i very disappointed with the service and i busy shopping for a new service provider who values clients. A word of month is a very powerfull marketing tool and i don't think in this case this will happen unless something drastic happens. Very Appalling service...
