Non-existent support for clients.

I have ordered a Fibre migration on Sunday 31st Jan 2021 and everything was in "Processing" according to my ISP. After Whatsapp support, a lot of phone calls and email support every single day asking what is going on they keep providing us with the same excuse that: they are still awaiting feedback from Frogfoot." We have submitted 3 or more times proof of residence and have been trying tirelessly to get Frogfoot to contact our ISP to give us feedback as to why we STILL don't have any connection..This is a MIGRATION, not an installation..What do you do if you have been tirelessly contacting and nagging your ISP and even try to contact Frogfoot directly only to get a response that they cannot deal with us directly they can only refer us back to the ISP but they NEVER respond to the ISP..... I work for an overseas company and like everyone else working from home and this is VERY URGENT to get this sorted.. What do I have to do to get this sorted? Because the problem is not the ISP but the provider to the ISP. If I could I would not recommend working with Frogfoot fibre because the support is non-existent. But we only can use them because they are the main provider. So if you are a contractor trying to get Fibre into a complex or estate...I would rather make use of a different provider..so be warned.
