CELL C POOR SERVICE - DECEASED CONTRACT

I am battling to close my late husbands contracts and transfer it onto my name. I went to the Galleria Mall, they really need to learn customer respect. they asked me to provide an affidavit stating my husband passed away in spite of me producing a death certificate. I then sent an email to creditqueries@cellc on 17th June. I have not had any responses until i sent an email on 21st June. they responded by asking me to provide my Documents that was required to transfer contract onto my name which was done @8.00am that morning. To date i have still not had any response. i called in and was told the only way to fast track this was to resend the email as they do not have a contact number??? Is this the level of service that we get from a service provider with so much competition out there. they want to make you cancel all contracts and move elsewhere
