Telkom stock problems

Eager to make us sign applications and contracts but never have stock. Have been waiting for stock (router) for a week. Phoning the store directly never helps as the line is always busy. The excuse is that they do not receive stock from head office. Why should we as customers accept this type of service. In addition I was showed a contract that was signed in November 2015 for which the customer is still waiting if I am to believe the sales representative. For one of the largest telecommunications companies in RSA you are really slacking Telkom. Not one of you would accept it if something you ordered was delayed so why should we, as your customers, accept it.
