Bad Service at it's level best

On the 22Sep14 I reported a ****** phone with Jabba Connect (cell c) as I have a contract with them. Najwa Customer Service Consultant sent me blacklisting forms and advised to fill the forms and send them back to Busisiwe with police affidavit, I did that on the 23Sep14, but never got a response from them. I called again Oct 14 I spoke to one of their consultant who advised I send the forms again to Busi, I forwarded the same e-mail but no one responded. I called Dec14 and advised that Busi went to leave and will only come back Jan. I followed up on January 15and only got a response then from Busi. I got my phone six months later on the 23 Feb but now struggling again to have my six months outstanding airtime to be loaded in my sim card, as Busi advised me to only buy a new sim then Jabba will do a sim swap and load airtime.The parties who are cc'd on my e-mails since last year are Busisiwe, Chantal,Fumane and Tsepo. This is a pathetic service that I am getting while my account with Jabba is up to standard, I have been paying for the services that I wasn't using for the past seven months and if I don't follow up with them they all just keep quite. Where is your customer service
