Bad customer service

Two years I took out a data contract with Telkom. Towards the end of the contract it was not connecting at all. Since it was expiring I took a decision not to renew it. The customer service was generally bad especially the staff attitude. Furthermore you could not avoid walking into the shop which I found time wasting and inconvenience. Around May I visited their Riverside Mall to note my non-renewal of the contract which was ending in June. After being made to wait at the door due to social distancing rules by the staff for 30 minutes I was allowed in only to be told by a disinterested staff member at the counter that they were offline. I pointed out that in fact I drove 38 kilometres from my home at Barberton and requested t write the notice of cancellation which would then be loaded online when their system was back online. I was told that that was not possible I should just visit their site and submit the notice. Telkom site is not user friendly I pointed out. However I was turned away. This morning I visited their Secunda shop to file the cancellation notice an i was told that I should give Telkom a month's notice which effectively meant that a contract that should expire in June would now end in July. I am unhappy about this since my earlier cancellation attempt was frustrated by Telkom. This is bad customer service.
