POOR SERVICE / NO FEEDBACK

On the 4th February I have e mailed ADT on the following e mail address [Email Removed] with a query on my account before I do a payment. On the 11th March I have e mailed another mail with again the same query and a cancellation request for service after phoning the office and was requested to use the above e mail address. (Proof of mails can be given) In my e mails I asked for my account to be explained to me - what's the amounts queried in the e mail - but no feedback was given, as well with the cancellation request. On Friday the 13th @ 12:01 I have e mailed another mail to a ZA Mpule while I was talking with her on the phone to confirm if my query was received and my notice was noted and received as well and if I can cancel the contract. At 14:34 I received a phone call from a lady with no info with regards to my query. Once again I asked for an explanation on what the amounts are on my account and if I can cancel the contract with ADT. This morning I received a sms stating: VALUED ADT CLIENT YOUR SERVICE HAS BEEN SUSPENDED. PLEASE CONTACT YOUR CREDIT CONTROL DEPARTMENT. KIND REGARDS. Firstly: WHY DO I NEED TO CONTACT THEM? E MAIL WA
