No service

Im very disappointed in the service from multichoice since mid August until now I have been battling with the same query. I was upgraded to a explorer 3 decoder which was suppose to be on price lock R649 compact plus package for 3 days after installation i didn't even have service because you guys were offline. Someone messed up and never put me on price lock that too another inconvience I am now paying a large amount which I have not agreed to and which is not my fault for my subscription I have been debited with R804 as opposed to what I was told I would pay. For the past 3 weeks this query has been escalated and im been asked to send smses because price lock has no number and 3 weeks same query I was promised that this will be corrected before my debit date guess what it never happened I called again today was told the same thing sms pricelock or go into a centre. What would it take to get some service because right now this service sucks and im very disappointed and frustrated at this stage that customers are treated like this im furious as well now that im being debited for an amount I never budgeted for the same query has still not been resolved. I need this sorted out asap
