Poor service

I have app**** for Wifi on the 28th of April 2023 since i have moved to the new house. The reply i got is that the previous owner didn't cancel the previous subscription they then requested me to send them the proof of address of which i did it but since then they don't reply to my email and i don't even have their contacts but they took my money when i app**** for that WIfi . so when i check my status on their website it says pending i am not too sure this pending its gonna last till when. I even spoke to the previous owner and he requested me to send me him the name of provider of which i did so currently i am still waiting till when i dont know.
