We still waiting

My dad app**** for wifi route for our house this was two to three months back,he had called the telkom shop at Hatfield for sometime now, but still his been pushed from pillar to post... We could understand when they told him there was no stock but up until today, its not acceptable... Why should the customer call and ask yet the company should inform us as the customers... Please look into this matter, as my dad is getting fedup
