Trash network coverage

Im so exhausted with paying rain whilst the network coberage is always down, ive moved the router around the house so many times that ive lost count, its the 2nd month paying for something that i can not utilize, i can not work like these, i want nothing to do with this *******! When i call i receive zero assistance but the debit order keeps on being deducted for a service i can't use. Im so jaged!
