Bad service

Have about 5 contracts with telkom,debit order is the 7th, debit went out and bounced back 4 days later. Contact the bank who say debit was rejected by telkom,then went to pay at woolies the account and unfortunately when i paid didn't notice that the cashier pit in R5 short. Few weeks telkim suspends account for the R5 shortfall, go back and paid even paid more,sent proof of payment to them a week now still my services are not restored. Tried calling sending email seems like i am getting quiet service from them. Thinking of canceling my services. Have been a loyal customer for more than 5years.
