Bad customer service and billing.

The company has a Bad tendency to disregard customer plight. After paying for a service (home Internet) l was told l paid late therefore l am not eligible to be allocated data bundles for the past two months. They still want me to pay for thosebtwo months l did not receive any data and pay for April too. I asked to speak to a manager but still today l am not allowed to speak to any manager to help me with my challenge. Bad turnaround times and no regard for customer support.
