No upgrade no reason

It has been 13 days since I first complained about Cell C. Since then I have been contacted four times by Client Liason telling me that she is investigating this matter. She can give me no feedback from their legal department as to why I cannot do an upgrade. Stating that legal does not answer her emails. Whow Cell C,internally you sure are in a mess if departments do not answer each other. I have been a customer for many years, debit order goes through every month, so what is the problem. Why don't I get an upgrade. Are you chasing you're existing customers away. Don't you need us any more. I send an email again yesterday-no answer.<br> <br> This is very bad service.
