Money Paid but no installation.

My worst nightmare, I app**** for a NEW connection on the 03 February 2025 via their sale assistance and they messed it up. They sent a link for payment and I paid but then, they reactivated an old connection that was installed by a tenant who cut the wires and took the router when she left. I contact the sales person and they advise that I get in contact with the service provide SADV which is very useless. I explained that this is a new application and there I require new installation, they advise that they have logged a call with Britelink and I will receive a call to confirm the installation day, till today, no feedback and no installation. I have tried to contact Britelink but their phone does not go through, I have escalated this so many times but nothing. This is the worst service I have ever experience. They are so *********** is disgusting. I have so many reference numbers but the last escalation they provided ticket no ***6.
