a very angry customer

i joined with Mobile plus. first they were late to give me my airtime, on the 27th Feb i called to activate my BIS, since then i haven't had any mobile network i have called in every day since the 2 March complaining as i don't receive phone calls smses or anything. <br> every time i call they tell me the same story that they will get back to me to date i haven't received any feedback. <br> they are quick to debit my account but slow when it comes to helping me with queries. <br> now when i want to speak to a manager they cut me off.<br> when i say i want to cancel they say i will pay early cancellation fees etc?? i am paying for a service that they are not providing! i have been with MTN for 6 years and i have had no problems a month with mobile plus and nothing but problems. i am really unhappy with this.
