Worst service ever

My name is onnicah Moeketsi,I made a geyser claim with absa.i had to wait for a week waiting for the geyser to be replaced .no one was keeping contact,I always had to call at my expense to find out the progress.they came on the second week after numerous calls,when they finally brought it,it had factory fault and they left it in my home and promised to come back.i have been waiting and I am so tired of the bad service received.i spoke to the guy by the name of Aubrey who promised to call me back on the 12th OCTOBER,I am still waiting for my geyser to be fixed even now.i have experienced the worst service with Absa I even regret having any relationship with them.Absa know nothing about customer service.
