Data usage and Customer Service

Hi there. Have 100GB data per month. As a responsible user I have downloaded a Huawei app to monitor my usage. App tells me I have 40GB left, but my account has been cut saying I've exceeded the 100GB. lodged with Customer Service, and they say they need 72 hours to respond. 72 hours later no phone call. No courtesy call either. Nothing. Call centre can only log problems. No direct line to Technical department. <br> <br> This is not acceptable for a service provider on both accounts. This conduct is ******* as stated in the consumer protection act.
