Wrong Bill amount

We have just recently renewed a new contract with yourselves. We have also changed the package however on our first bill since the package I have £75 worth of fees ie connection fees which was not discussed over the phone and I certainly didn’t agree with (please refer to call if recorded). Also when we received our new broadband hub it was faulty! So rang and spoke to someone who said their wasn’t any extra charges (which the monies has now come out)! Along with this we had no broadband for 2/3 days till technician came out and swapped the box so we should be due a credit for being offline which is suppose to be automatic. Please look into this.
