INCORRECT BILLING WITH POOR SERVICE EVER AFTER

Biling issue wid TELKOM.Afta inquiring I checked dat dey hav now increased my monthly subscription of my R169.00 contract to R456.50 which is totally wrong. Dey hav not sent me any communication regarding dis price increase. Dis is not new2me as I do knw Telkom process very well n dis is a daily issue.I called da call centre on da 04/11/2015 n spoke 2 Sifiso Manana who logged a case.I hav called n emailed him eva since bt hav nt even gt a courtesy cal or mail. I called again n a lady on da 12/11/2015 advised me dat she sent da manager Brenda Jacudo a mail 2 contact me n 2 date no response. I called 2day and spoke to Petronella Mthethwa who said she cannot assist n wen I ask for da manager she rudely cut me off.I called again at n spoke2 Siphesihle Mkhize who advised me she has escalated dis case again. Telkom need2pull call recordings.I realy think dat these ppl dnt belong in a customer service environment as dey dnt knw how2deal wid customers. As 4 team leaders if dats da way u lead den dat wil explain da Pathetic Service dat Telkom provides.Da Area Manager Gugu Khumalo need2check on dis bcos Telkoms main focus is customer service bt2me it luks lyk dis is da last focus....
