Pricelock - pathetic service

I requested a quote to terminate my DSTV pricelock deal in November. The query was escalated to the Pricelock department (who you apparently cannot speak to) and I was promised the quote within 48 hours.

I have followed up with calls to their call centre (at least 3), I have liaised with them via their twitter account (10 messages or more) yet still, 3 weeks later I wait for this quote. To compound matters, they turned off my DSTV feed for 2 weeks.

With each interaction I get the same response: "We apologise, and we have escalated the request again". This is pathetic!! DSTV are taking their customers (long-serving) for a ride, yet quite happily collect their R900pm. Their latest pathetic response is that "there is currently a backlof in Price queries, we will get in touch with you". No time frame given. Rest assured, they will not!

What am I supposed to do to get some service!!!??? DSTV, up your game, this is a disgrace!
