Escaping accountability

I recently visited a telkom store to get my line transfered to another address, at the store I was advised to apply on the online form in the store which I proceeded to do and was told I would get an sms to confirm my transfer. A week went by with no confirmation I decided to go to a telkom store to enquire. There I was told my order wasn't put through due to them not being able to confirm the address I had used because the apartment was on a corner of two streets. My address was corrected then the order put through. upon receiving the date for my transfer It was too late as I'm moving out of the property on the 20th. I called the call centre and was on the line for 50 minutes with 3 different people trying to get my problem resolved. Was given the magical \We'll escalate it"answer and no time frame what so ever as to when my request will be processed. Upon insisting on at least a time frame for the response I was told no promises can be made as to when the technical department will reply which is escaping responsibility for the mistakes made by telkom and not giving me a time also means they can not be held accountable when the service is bad."""
