Poor service!!!

1) I have repeated attempted to reach your offices by telephone, however, I am kept on hold indefinitely, sometimes for more than 10 minutes at a time, and till this day, no has attended to my calls 2) I have attempted to reach your offices again today, and my call is either placed on hold until I give up, or it doesn't get through at all. 3) I have only just recently taken your Beamie product (in July), and I already have to pay an annual price increase! I have only just taken up your services, how can I already be paying an ANNUAL increase in my first two months of being your customer. 4) My price plan was increased to R70 a month from R59 a month without my consent (or request)!! 5) What is the fastest way of cancelling my services with you? I no longer wish to be affiliated with your company if this is the level of poor service I am going to receive.
