DSTV price lock

I took the March price lock and to date they are yet to activate the price lock on my account all "because there was a problem with the system at the time" now because of someone's negligence and incompetence I have been paying more than what I should have been for the past three months, further more when I phone to put my account back on debit order because now all of a sudden it's no longer on debit order?!? the price lock department doesn't phone you back... oh and they don't take calls either! So now I'm sitting with a price lock decoder and dish, my account has been suspended for the third time in a row and the supervisor that "promised" to get back to me before the end of business today didn't bother to call me back, so now what should I do???
