Bad service

My Contract expired on the 1st of November, i decided to renew my contract but instead my application was cancelled without any communication with me because telkom didn't have stock and had to visit a store in person. i was so upset because nobody told me until i had to call them i was taken from pillar to post. i was promised to be send a black Friday cataloque to choose something different by a supervisor in the upgrades department but still nothing has been send to me. can just telkom be straight forward with me please that they dont need my business. damn your service sucks and you dont respect customers.
