Terrible line speeds

<p>I was sold a LTE package and promissed speads of up to 150MBPS, at absolute best my line is capable of 18MBPS and ussually syncs at 9MPBS on a very good day. Totally unacceptable and your technician that was at my premisis today has also confirmed to me that the coverage area has now changed and i fall outside of this. How is this possible?</p> <p> </p> <p>Your call centre simply just cut me off when i call to ask for help.</p> <p> </p> <p>Please confirm the process of cancelling this contract UNLESS you have solution, this is not what i am paying for at all.</p>
