BAD SERVICE AND DELAY IN INSTALLATION

I place an order last month order number ********** 31A

Today 3 May 2018 I called Telkom to follow up on the order and I was told that the order has been cancelled ( ********** ) because they could not get hold of me. The agent I spoke advised that that the system shows that some tried to call me on 21 April 2018 to confirm installation date I have gone through my call logs and to my surprise I see no record of this call.

Telkom please advise if you will be able to assist me or should I look for another service provider ASAP.
