Mweb SUCKS

My account has been recently suspended for missing documents, which we sent to the company on delivery of my LTE products. they made a call to me on 6 Apr (no message) and suspended three days later. After 1.5 hours of speaking to various call centre agents in (billing, sales, customer services and technical support) none can assist nor retrieve the documents they asked to be emailed. I've since requested that they cancel my account and again none of these departments can help as it is all not in their scope. My monthly billing continues though... with no service
