It's a shambles. More than three weeks to get someone for a non-repair

My Bosch Tumble Dryer is under rent-to-own since January 2020. The condenser tank sensor reported an error. I reported it as faulty online in the last week of November. I phoned on the 28th of November when I heard nothing. The technical department logged a repair. I heard nothing and phoned on the 5th of December to follow up. The person informed me that the proof of purchase wasn't sent to Bosch and had escalated to finance. I phoned again to follow up on the 8th and 12th and got the same reply. Then I spoke to customer care on the 14th and they suggest that only Technical can handle it. I phoned Technical and after explaining everything again and asking to speak to the manager, the person relayed it to the manager and then said that a technician will be sent. On the 15th the technician came to resolve the situation and said a pipe was blocked causing the problem. I was only able to dry washing again on the 16th and the same sensor error came up after about 20min. I waited for the dryer to cool and tried again with a smaller load on the low heat option and it took about 20min before reporting the same error. I reported the repair as incomplete. I phoned on Monday the 19th and spoke to the service manager to ask about resolving the problem and why the proof of purchase took so long to resolve. He then said the dryer isn't under warranty anymore and that Teljoy technicians were assigned and will come out again.

We have been Teljoy customers for more than 20 years. This is unacceptable. I previously had Defy appliances and Defy technicians were sent while the appliance was still under rent-to-own.
