Fibre nightmare

I have been waiting approximately 5 weeks for fibre with no joy. Spent 30 minutes on the phone to ensure there is light at the end of the tunnel before oredering. Connection was assured and now waiting 5 weeks. No managers to speak to as you will be placed on hold for 20 minutes with no luck. This is the second ISP i have tried and have been waiting for 3 months in total for fibre. the worst part is that there is a fibre line in my property which belongs to openserve. The Sense of urgency is no where to be found. Only another number to them. The word ESCALATED only means you have to wait another week for a unacceptable answer.
