No service

In Dec i received a sms saying i qualify for a discount on my acc. I email Kgomotso asking abt the discount as i extra money that money no response. I called on the number no answer. Called call centre enquiring abt this the lady said she will escalate someone will call me in 24 hours no call. In Jan again i receive a sms regading discount respond to email no responce wat so ever from Kgomotso. Abt a month ago i realise my debit didnt go of because my agreement with them for the period prob expired and we needed to put a new agreement in place. I send an email to ask that the debit order be reinstated as the acc would most prob be paid up Aug/ Sep no answer what so ever. I chat online with a consultant regarding a complaint email add. Even the email add for complaints was wrong as the email was never delivered. How am i suppose to get any service from the company if no one is willing to assist.
