Refund of order not done and no resolution

Online order had to be refunded on the 20th of November 2025 They delivered the microwave again on the 9th December 2025 when I specifically said I wanted a refund. The microwave was tested again and still faulty. The store is of no help, after numerous calls and not being assisted or the calls not being answered. The call centre is hopeless and never gets back to me. I don't want the microwave and want my refund. I have been escalating the matter without any assistance. I will go take that microwave and throw it in the store and demand a refund. They are wasting my time and the management is pathetic at the Ottery store. Deon who is the manager asked for my order number and said he will call me back. This was on the 11th December, still no call back on the 11th and I had to call the store back to ask for him and there was no answer. I had to waste my airtime, time and energy dealing with this BS!
