No hot water for 2days

Good Day,please note that on tues a kwikot technician came out 2 repair my geyser and replaced my thermostat and element, the next morning there was still no hot water,I contacted the call centre (***) to which samson was 2come out,i spoke 2 jan the supervisor and asked him 2contact samson 2ask him if he was coming out,jan did not get back 2me till today. I have an 8 month kid in the house and we need hot water. 2days is unacceptable. Its going into day 3 now. I'm extremely disspaointed with Jan (Supervisor) for not resolving my query and getting back to me.
