Teljoy most pathetic service

My air con had been leaking since December, the unit was removed and taken to a warehouse for repair. 5days later it was reinstalled, however they broke my airvent and damaged paint on walls. Few days later it started leaking water badly again damaging walls and plug point. I logged a call again. This time they told me unit cannot be repaired and,need to be replaced. It is now February I am still making monthly payments and to date dint have a working air con. I escalated it to Octavia the team leader who then escalated to Brenda her manager and until now keep getting the run around. I am paying teljoy for an appliance that has not been working since December. Summer is almost over and teljoy has actually just ****** me by still taking my money and not providing a service. Worse off they have caused damages that I am paying to be repaired. Most pathetic service ever.
