Overcharged and empty promises!!!

I have sent you two previous emails regarding being overcharged because of a mistake from your part. When I asked for the umpteenth time why the wifi was so slow, the person assisting me told me that my Huawei router was no longer in use and that was why it was not working. I requested for the "theOne" package and router, AS WELL AS the removal of the Huawei router, as that contract will no longer be in use. TWICE NOW I have been charged for BOTH contracts even though I am only using the "theOne" router and the Huawei has still not been collected, meaning I was overcharged by more than R1000!!!!!

I was assured that the issue will be escalated to accounts to be sorted out, but nothing has been done.
