PATHETIC SERVICE AND UNAUTHORIZED DEBIT ORDERS

So I join them, with a guarantee of 6 weeks until installation, after nothing I phone them a lot of times and email - no resonse. Finally - sorry mam you have been postponed for two more months... I tell them to cancel my contract and come get their modem as I will move to a reliable servie - yet they then IGNORE me for two weeks, and then ***** my money as they debitted my account for the modem they am suppose to come collect! After that they still ignore me, spam me with ********** 00's of sms'es telling me they will get back to me, but yet nothing. I phone then they will phone back, I email - ignored, So how am I suppose to get my money back for a product and service I dont want AFTER THEY BROKE THE SERVICE AGREEMENT. I NEVER GAVE PERMISSION TO DEBIT MY ACCOUNT FOR ANYTHING A WEEK BEFORE PAYDAY - FOR A PRODUCT THAT IS THEIRS AND AM WAITING TO BE RETURNED TO THEM.. THATS THEFT AND I WILL REVERSE EVERYTHING BUT STILL!!!! PATHETIC!!!!!!!!!!!!!!!!!!
