Bad service

We purchased an AEG Dishwasher from Game Watercrest about 14 months ago and it started to leak water profusely in April 2021. We luckily purchased an additional 2 year guarantee so our dishwasher was still covered for repairs. To say that the service we have received has been shocking is an under statement. We reported the problem on 26th April and to be fair, a service technician came promptly to assess the machine and report back to the Service Department . To date we have not heard back from the company. My husband has phoned a lady called Emmerentia, who has on numerous occasions, promised to give my husband feedback but to no avail. Apparently, there are parts available for the machine in South Africa. We were promised that the machine would be repaired by no later than Monday, 17th May but to no avail! My husband has also spoken to Peter Pretorius, the service manager who was very helpful but now his phone also goes to voicemail. Quite frankly, the service we have received is totally unacceptable. No after sales service is very evident!
