Very Bad service delivery to customers.

I ve experience very bad service delivery from Multichoice dstv for 2 months .After i have paid my account in January and switched to a other package my channels was never switched and my T.V. was disconnected when calling telephonically to find out what was the error.After reporting it at the cashier she connected my channels again .This happened 4 times . The reconnection fees reflect now on my account .Currently my TV is disconnected again after i went to my branch and after it was disconnected they told me that there was no payment for february which means that the account is in arrears. I was given time to pay again on 10.03 .My normal payment date is 20.th of each month how is it possible that a receipt was given to me but a payment is not reflecting on your systems.That payment never goes through their system same as the previous months switch and the cashier should have told me to make a cash pament .But she did not notice it and they just disconnect my T.V .This is unacceptable service and dont care attitude towards customers .so Multichoice can disconnect your channels as they wish at any time without notifying the customer the same time when a paymnt is outstanding why did they wait until 10.03 18 ?
